Precision Twist Drill Cobalt Jobber Length Drill Bits - Split Point

Precision Twist Drill Cobalt Jobber Length Split Point drill bits are heavy-duty twist drills for metalworking and general fabrication. Jobber length is the most common drill bit length, so these bits suit a wide range of drilling jobs. They are made from cobalt high speed steel for added heat resistance and longer tool life in hard, tough materials.

Key Features:

• Cobalt high speed steel construction: holds up to heat better than standard HSS and lasts longer when drilling hard materials.
• 135-degree split point: self-centering, so it starts without a pilot hole and resists walking. It produces small chips that help prevent clogging.
• Low thrust design: makes it easier to penetrate the workpiece.
• Oxide finish: helps carry cutting fluid and resists wear. It also helps prevent chip welding on ferrous materials.
• Round (straight) shank and spiral flutes: fit standard drill chucks and clear chips as you drill.
• Industry standards: made to ANSI standards and NAS 907 specifications used in aerospace.

Applications: These bits work well in hardened and tempered alloy steel, stainless steel, cast iron, titanium and high-nickel alloys. Use them in drill presses, hand drills and other machine tools, for production work, maintenance and repair.

Precision Twist Drill is a respected name in industrial cutting tools. These cobalt jobber drills give machinists, fabricators and tradespeople dependable, repeatable hole quality.
