Screw Machine - ThunderBit
Triumph ThunderBits are high performance drill bits. Made from industrial grade high speed steel finished in black and bronze oxide to extend the life of your tool. The unique spiral flute design improves chip ejection and allows coolant flow to point. 135 degree split point reduces walking and scarring on your project surface. Specially heavy duty construction means a longer life and a tougher tool.
