ProMAXX Tool machine-shop-grade tooling bits are ground at 135° cutting angle (lip) with a split point. Flat ground bits cut slower and are long lasting but less accurate and will walk while drilling. Split point ground bits will stay on center to reduce walking because they have four cutting edges and distribute loads better. They work well on curved shapes and alloy and stainless steels because it creates smaller chips to minimize clogging holes and breaking bits. It also has a thinner web, requiring less force, because there is less heat and less chance of work hardening.
Drilling through extremely hard material including titanium, boron, ultra-strength, and even stainless steel is easy with ProMAXX Tool's premium gold drill (tooling) bits. Exceeds aerospace specifications. These are the best drill bits for drilling out exhaust studs and more.
High-performance tooling bits engineered to cut through the hardest materials and drastically increase productivity. Excellent for drilling extremely hard materials including broken extractors and taps. Also great for exhaust manifold repair, water pumps and valve covers.
