Solid Carbide Screw Machine Drills - Cont.

Micrograin Solid Carbide

Heavy Duty 135 O Drill Point Slow Helix

• Slow helix • Split point improves penetration • Shorter flute and overall length increases rigidity, resulting in less deflection, better hole accuracy, and longer drill life • Can withstand high drilling speeds and temperatures. • Suited for materials such as nickel and chrome alloys, steel weldments, titanium alloys and stainless steel
