#1 Counterbore – Solid Carbide TiAln Coated


7 in stock

Categories: ,


We have these counterbores custom made for us by one of the top tooling manufacturers here in the USA.

These are a solid pilot  TiAln coated solid micro grain carbide  counterbore. They are built to work with our 1-72 short socket head titanium screws.

These are tighter than a standard #1 counterbore and will leave a .005″ clearance around our screw heads for a clean precision fit and look…


TIP:  Do NOT clamp down the part you are counterboring. These do not like to flex . Hold your part free and you will get awesome results. We have counterbored hundreds of holes and are still using the very first one we ever bought!!!
