Product Overview
"Z" SLOW HELIX 135DEG DRILL - 720
Slow helix 135° split point provides ease of penetration and increases edge strength. Heavy-duty web, short flute and overall length increase strength and rigidity.Solid Carbide ideally suited for drilling difficult materials (up to Rc 60).
Features
- Solid carbide construction for extreme rigidity and strength
- Carbide base material can drill up to 2x faster than HSS
- Self centering 135° split-point for reduced thrust requirements and minimized walking
- Bright finish for added lubricity
- Shorter screw machine length adds rigidity to the drill bit to reduce breakage
- Round shank
- Made in USA
Applications
- Drilling in very high strength materials like cast iron, steel, and bronze
- High performance drilling
- Drilling with fixed spindle machines like CNC mills and drill presses
- Drilling in sheet metal
