Double flute bottom cleaning straight bit

Carbide Tipped with bottom insert

A special-design straight router bit with a bottom cutter insert. Unlike common mortise bits, these bits feature a special overlapping centre carbide tip design which guarantees you a smooth and clean bottom cut every time. Ideal for cutting or cleaning out dadoes, cutting stair treads into risers, and putting stress relief on the back of mouldings. Great for making wood signs as well as removing paint or varnish.

This is a great bit for creating 'stress relief' areas in backs of large and long trim mouldings like skirting. These bits are two flute, carbide tipped. 

Use a two-flute bit where fine finish is paramount. Two flutes balance the bit, eliminating vibration that degrades the cut finish.

Two cuts per revolution yield a smooth surface, but feed rate is slightly reduced.

This router bit has a 12.7mm shank (shaft) that will fit most large routers. Please ensure that you select a router bit with a shank (shaft) size that will fit into your router collet.

 

PRO-TECH router bits are manufactured in Taiwan.

General safety suggestions:

It is advisable to always have the following items nearby and in a good condition

  • Eye protection clean and scratch free
  • Hearing protection quality earmuffs
  • Dust masks discard old and dirty masks
  • Gloves for easy handling of material and hand protection
Wear Gloves

To use router bits safely (and to get the best results from your router), the router bits need to be installed properly into the router's collet. Improper installation of your bits can cause excessive chatter and could increase the likelihood that the bits will break when in use. 

Clean and sharp

First of all, before beginning any routing operation, check your bits to make sure that they are clean, relatively free of pitch, and most of all, sharp. If the bit is dull, chipped, is excessively burned or has any other defect, it should be sharpened or replaced before use. 

Correct collet and collet nut fit

Most router collets have a recess (groove) that needs to click into a circlip that resides inside the collet nut. Failing to ensure that the collet 'clicked' into the collet nut will cause you to struggle to remove the router bit after tightening. This could cause the collet to break or be removed by a technical repair centre.

 

Correct fit inside the collet

When installing the bit into the collet, do not tighten the collet with the bit 'seated.' Instead, insert the bit until the shank (bit shaft) reaches the bottom of the collet, then ease it out about 2 mm before tightening the collet.

When the bit is tightened, there should be no less than  2/3 's of the length of the shank in the collet. If your bit has a shank that is too short, then the bit should be replaced. 

 

Safety gear

There are a few other safety measures to keep in mind whenever you use your router. First of all, remember to always wear appropriate safety gear as indicated above.

Correct speed setting

Second, be sure to set your router to the proper speed for your router bit. Setting your router to an incorrect speed will not only affect the router's performance, but also can cause the bit to break much more easily and even cause bodily harm. The speed at which a router bit turns can be important. The typical router runs at about 22,000 rpm, which is fine for most bits. But as the diameter of the bit increases, you ll want to slow things down.

Also, before beginning any routing operation, be certain that you give the router's motor time to come up to full speed for the chosen setting. Beginning to cut before the bit is at full speed can give less than desired results. 

Observe the following at all times

  • Wear a protective face shield or Safety Glasses to prevent eye and face injury.
  • Wear ear plugs or ear muffs to protect your hearing.
  • Use a respirator or dust mask to give protection from dust particles. Wood dust may remain in the air for hours after using power tools.
  • Always read and follow router operator's manual instructions.
  • Make sure that router rpm's and the bit selected match.
  • Dress properly. Wear short sleeves, no loose fitting clothes, proper footwear and no jewellery. Tie back long hair.
  • Always be sure the router is unplugged before replacing bits and that the switch is off before connecting the router.
  • Be sure the router bit has completing stopped spinning before sitting the router down.
  • Be sure bits, clamps and attachments are secure before starting up.
  • Keep children, pets and visitors at a safe distance.
  • Be especially cautious when working small pieces.
  • Keep hands and fingers away from revolving bits and cutters.
  • Do not operate routers in moist or wet areas.
  • Always grip tool tightly and be prepared at start-up to resist the motor torque.
  • When using a router table, make sure on/off switch is easily accessible.
  • Learn the sound of your router and shut it off at any unfamiliar sounds or irregularities.
    Never start the router with the bit in contact with the material.
  • Always feed in the proper direction, against the direction of bit rotation.
  • Maintain equipment. Replace worn parts, discard worn-out bits and check router periodically. Clean parts with appropriate solvents.
  • Don't operate a tool if you are tired or under the influence of medication, drugs, alcohol or while smoking.
  • Check wood for nails, screws or loose knots before routing.
  • Keep your mind on your work, avoid distractions, work at a comfortable pace and stop before you get tired.

Do a dry run

  • Place the router on the final work surface and test you cut by moving the router over the whole are to cut with THE ROUTER SWITCHED OFF
  • You do not want to waste an expensive piece of wood
  • You do not want to start all over
  • Never met anyone with spare fingers - SAFETY

"Inside Blizzard: The Creativity, Crunch, and Corporate Clash in Play Nice”
Format: Hardcover
Positive: "Play Nice" by Jason Schreier is a fun, eye-opening dive into the highs and lows of Blizzard Entertainment. Schreier does a fantastic job unpacking the tension between Blizzard's creative magic and the corporate pressures that started to shift the company’s culture, especially after its merger with Activision. It's filled with juicy insider stories that give you a sense of what it’s really like to work at a powerhouse game studio. For any gamer or industry enthusiast, it’s a fascinating look behind the curtain that also feels relatable for anyone who's had their passion collide with corporate demands. Negative: On the downside, the book sometimes gets a bit repetitive. Schreier really drills in on the company's struggles with work-life balance and workplace culture, which are important but can feel like they’re hitting the same notes over and over. And while the insider jargon adds authenticity, it can be a little hard to keep up if you’re not already familiar with game dev lingo. But honestly, these are minor gripes in what’s otherwise a great read about the complex, often messy reality of making games.

From Pixels to Problems! Great read!
Format: Hardcover
“Play Nice” offers an enjoyable deep dive into the tumultuous history of Blizzard Entertainment, chronicling its journey from a ragtag group of brilliant college students to its evolution under corporate ownership and its current state. Schreier provides fascinating insights into the antics of Blizzard’s early employees, showcasing their outlandish attitudes, relentless work ethic, and tight-knit camaraderie. The book explores how Blizzard transitioned from a company renowned for producing high-quality, polished games that left competitors in the dust to one struggling to preserve its heart and soul amid mounting corporate pressures. While the corporate side and C-suite executives are often cast in a negative light, Schreier thoughtfully examines the motivations behind their decisions, offering perspectives from all levels of the company—from executives and middle management to QA testers. This balanced approach provides a refreshing take, avoiding oversimplified blame and instead considering multiple sides of the story. And while it’s easy to villainize the suits in the boardroom, Schreier does a great job showing why some decisions were made. From executives to QA testers, he pulls back the curtain to reveal a mess of perspectives, reminding us that every bad decision has some kind of reason behind it (even if it’s still a bad decision). The book also revisits the scandals that put some serious smudges on Blizzard’s reputation, offering new angles and fresh commentary. As someone who once lived for Blizzard games—cheering at Overwatch League matches and losing entire weekends to Diablo marathons—I can’t help but root for Blizzard to find its way back to glory. And hey, if it means waiting another decade for their next masterpiece, so be it. It’s done when it’s done.

Great insight into an otherwise obscure world
Format: Hardcover
As someone who grew up playing blizzard's games for an unfathomable amount of hours I've always been interested into their inner workings, especially considering their downfall in recent years. This book holds a ton of information and knowledge, is well sourced, and is the work of someone with obvious deep familiarity with the industry and its particularities. Besides the information itself, the book it written in fun and interesting prose, and it keeps the rhythm fast and entertaining, so it reads more like a novel than a journalistic article. Overall, an entertaining piece of insight into a world that is normally quite unknown, even to long time gamers like myself.
