Walter 01H032 SST+ 135° Point Cobalt Stub Drill Bit, 1/2"

Walter 01H032 SST+ 135° Point Cobalt Stub Drill Bit, 1/2"

Excellent for drilling into sheet metal and other thin-walled material. Its split point of 135° allows for positive drilling without center-punching and its short length gives high resistance to breakage and allows for drilling in confined spaces.

Product Features

• Made with premium grade cobalt HSS to drill harder materials
• Cobalt drills can drill approximately 30% faster than HSS drills
• Self centering 135° split-point for reduced thrust requirements and minimized walking
• Special bronze SST surface treatment for extreme lubricity and life
• Shorter length adds rigidity to the drill bit to reduce breakage
• Round shank

Applications

• Drilling holes in high strength materials
• Heavy-duty drilling
• Drilling in sheet metal
• Drilling with fixed spindle machines like CNC mills and drill presses
