Flexible honing with the Flex-Hone tool produces an oil holding cross hatch pattern and a true plateau finish free of cut. torn and folded metal. Any type or size of cylinder can benefit from the Flex-Hone. These abrasive bead style brushes are produced in standard diameters from 4mm to 36 inches. Nine abrasive types are offered including silicon carbide. aluminum oxide. boron carbide and diamond allowing the tool to be tailored to finish any base material. A choice of 11 different grit selections are available for precise control of finish parameters. The elimination of peaks results in rapid ring seating. better oil control. reduced seepage in hydraulic and pneumatic applications and provides better seal performance and longer seal life. Successful applications include firearm chambers. shotgun barrels. musical instruments. combustion chambers. air compressors. pumps. valve bodies. valve guides. brake cylinders. wheel cylinders and the list goes on and on. Flex-Hone tools are also very effective for deburring cross drilled holes. port radiusing and edge blending. Because of its unique construction. the Flex-Hone is self-centering. self-aligning. and self-compensating for wear so it does not require an elaborate set-up or special training. Deburring can be effectively automated and combined in the machining process to allow a complete cylinder finish in one operation or it can be employed as a secondary operation with equal results.

Features

  • Flexible abrasive cylinder hone for surface finishing and cross hole deburring

  • Self-centering. self-aligning. self-compensating for wear

Asurion worked as intended.
After three years, my monitor failed. Asurion paid to send it to a repair center. I didn't save the box the monitor came in, and paid $23 to have it packaged up. They kept me informed of the various steps, such as en route, arrived, testing, and repair started. They discovered it could not economically be repaired and refunded my purchase price. The entire process from me telling them it was broken until the refund took 5 days. I am well satisfied with the service.

Excellent, prompt, zero hassle protection
I purchased a nice 3D printer for my grandson. He was thrilled and he and his dad used it frequently. The printer developed a serious problem but, thankfully, I had also purchased a three-year protection plan with Asurion. We shipped the printer to Asurion via UPS since they readily agreed to repair it or refund the purchase price. After only a few days, Asurion emailed me that the printer was not repairable. They sent me a link that enabled me to send the full purchase price to my Amazon account. I used it to purchase another printer. I am happy and my grandson is thrilled! I should add that the extended protection did not cover sales tax, nor did it cover shipping cost.

Strongly recommend
I recently used the services of this company, and I was completely satisfied. They work very professionally: whenever I reached out, they quickly resolved any issues. I strongly recommend that anyone who purchases electronic devices register their product with this insurance. It is truly reliable.

Cheap Insurance - Easy Claims Process!
I bought this warranty plan for a Dell monitor about 3.5 years ago. About a month ago, it started to give me some intermittent problems (very fast flickering & image retention). I tried everything I could to troubleshoot the issue, but it just kept coming back. I had some issues with logging into my Asurion account because I used an EDU email, which I no longer have access to. I sent a message to Asurion here on Amazon and they sent me my plan details and everything I needed to make a claim within 24 hrs. Once I was able to log into my account online, the claims process couldn't be faster/easier. I used the chat function and provided the rep with the issues I was having with my monitor. The rep immediately emailed me a pre-paid UPS label to send my monitor to one of their repair facilities. I got another email when my monitor was received stating that repairs could take up to 5 business days. However, the very next day I got another email stating that my monitor couldn't be repaired and they would be reimbursing me the full purchase price. I received another email with an Amazon gift card for the full price of the monitor within minutes. This is my first experience with Asurion and I'm very impressed. The customer service is top notch. If I ever buy another expensive electronic item from Amazon, I'm definitely buying an extended warranty from Asurion.
