Chicago-Latrobe, 69885, Style 159 #1 - #60 Wire Gauge Drill Set, Heavy-Duty

Features

• Heavy-duty geometry for drilling tougher materials by hand or machine.
• Shorter flute and overall length provide superior rigidity to minimize deflection when using heavy feed rates.
• Manufactured from premium high-speed steel.
• 135° P3 split point is self-centering for reduced thrust and easier penetration. Sizes under .0625" do not have split points.
• Black oxide and titanium nitride (TiN) finishes standard from stock.
• Black oxide surface finish increases wear resistance and adds lubricity, improving chip flow.
• Titanium nitride (TiN) PVD coating adds lubricity and hardness which enhances chip flow, finish hole quality, and drill life.

Application Information:

• tool steel (black oxide, TiN)
• alloy steel (black oxide, TiN)
• carbon steel (black oxide, TiN)
• cast iron (black oxide, TiN)
