Saber HSS-Co5 (Cobalt) TiN Coated Cross Hole Round Shank 90 Deg. Countersink SetSaber HSS Co5 (Cobalt) TiN Coated Cross Hole Round Shank 90 Deg. Countersink Set For countersinking and deburring in a wide range of materials including ferrous and non ferrous metals. The intersection of the hole and cone form the cutting edge on the tool.

- Saber HSS-Co5 (Cobalt) TiN Coated Cross Hole Round Shank 90 Deg. Countersink Set
- For countersinking and deburring in a wide range of materials including ferrous and non-ferrous metals.
- The intersection of the hole and cone form the cutting edge on the tool.
- The cone is not truly symmetrical as it is essential that the cone retreats away from the cutting edge as the tool rotates.
- If this does not occur the cutting edge will lack clearance and rub rather than bite into the material.
- This clearance is referred to as cutting relief.
- The radially relieved single cutting edge provides fast stock removal with low vibration for chatter-free operation ensuring the smoothest finish.
- These tools are best used as deburring tools, where a burr, or sharp edge, from a previous machining operation needs to be removed for cosmetic and safety reasons.
- They also may be used in softer materials (such as wood or plastic) to create a countersunk hole for a screw.
- HSS-Co5 (Cobalt) countersinks are extremely hard and provide superior performance and increased tool life especially in stainless steel and high tensile steel.
- Bronze Finish (gold oxide) surface treatment. The metallic brown coloured low temperature temper treatment is normally only used on cobalt tools for identification purposes.
- Gold Finish TiN Coating (Titanium Nitride) helps to dissipate heat and reduces friction and cold welding.
- The coating higher speed and feed rates can be achieved and tool life is greatly increased.
- The TiN coating is achieved by Physical Vapour Deposition (PVD).

Best heat shrink tubing on the market
Stop buying the kits with multi sized heat shrink tubes. Don’t buy the 5’-10’ pieces that arrive folded up and as thin as scotch tape. This stuff is nice and thick, it shrinks evenly, and my favorite, it is lined with glue on the interior. This is a 65 foot roll of 3:1, high quality heat shrink tubing. I will never go back to the kits that say 400 pieces and 300 of those pieces are only big enough to heat shrink some thread or a strand of hair. I have purchased 2 sizes and I use it 3-4 times per week and I don’t think I’ll ever run out. This is one of my favorite discoveries of 2023. Before buying a kit, think about how many sizes you really need. I can do all of my AC 120v and DC 12v wiring, which consists of 4-5 sizes of wire, and I only need 2 sizes of heat shrink tube for all of it. It’s oddly satisfying to watch this stuff shrink and see the glue squeeze out of the ends. Definitely ASMR.

Where Has This Been My Whole Life
Maybe I've been living under a rock, but I didn't know you could buy better quality heat shrink that is thick, has a water proof glue, and shrinks a true 3x. I've been using the junky heat shrink from local stores and the bulk packs sold online that are precut, barely shrink and don't have any glue. Well, after digging and finding this, I'll never go back to that regular heat shrink again. This will fix 12 gauge extension cord, down to single wire if necessary. It's also really thick and with the glue, gives a lot of confidence in your repair. The 1/2" size I got seems to fit most things I work on just fine, but I might get a size bigger and smaller later for other projects. Overall, I'd highly recommend.
