STRONG JOHN 1/8" x 1 5/8" HSS COBALT DRILL BIT

Drill cleanly through hardened metals and abrasive alloys with the Strong John 1/8" x 1-5/8" HSS M35 Cobalt Drill Bit. Engineered with an industrial-grade M35 high-speed steel alloy containing 5% cobalt, this drill bit withstands severe friction and extreme cutting temperatures without losing edge hardness. The precision-machined 135-degree split point starts instantly on contact without "walking," completely eliminating the need for center punches or pilot holes. Featuring a 1-5/8" flute length for rapid chip clearing and a 2-3/4" overall length, it delivers smooth, vibration-free hole-making across stainless steel, structural carbon steel, cast iron, non-ferrous metals, dense plastics, and wood.

Key Features:

• M35 Cobalt Steel Alloy: Enhanced heat and abrasion resistance for extended service life in high-tensile and work-hardening metals.

• 135° Split Point Tip: Self-centering point penetrates immediately on contact without skating or needing a pilot hole.

• Precision Chip Removal: 1-5/8" parabolic flute design channels metal shavings away fast to keep cutting temperatures low.

• Vibration-Dampened Performance: Rigid web construction minimizes bit deflection and chatter under heavy drilling pressure.

• Multi-Material Capability: Optimized for stainless steel, iron, structural steel tubing, brass, aluminum, PVC, and hardwoods.

• Standard Specifications: 1/8" drill diameter, 1-5/8" usable flute length, 2-3/4" overall length.
