Value Collection 01-020 Cobalt Jobber Drill Bit No. 20

Product Description

The VALUE COLLECTION 01-020 is a cobalt jobber-length drill bit sized to wire gauge No. 20 (0.1610 inches decimal), designed for general-purpose drilling in demanding materials. The 135-degree split point reduces walking and requires no center punch on most surfaces. A straw finish indicates the cobalt content that gives the bit heat resistance during high-speed drilling. At 3.25 inches overall length with a 2.125-inch flute, this is a standard jobber geometry suited for bench drills, hand drills, and CNC applications where a short-to-mid reach is appropriate. Two regular spiral flutes evacuate chips efficiently during through-hole drilling.

This bit is engineered for right-hand cutting in stainless steel and other hardened materials where high-speed steel bits typically fail prematurely. The straight cylindrical shank at 0.1610 inches diameter seats in standard three-jaw drill chucks without adapters. Typical applications include fabrication shops, maintenance facilities, aerospace assembly, and any trade work involving fastener holes in stainless sheet, angle iron, or hardened plate. The Series 01 designation places it in a heavy-duty grade product line built for repeated use rather than single-job consumption.

Key Features

• Cobalt construction resists heat buildup during drilling in stainless steel and hardened materials
• 135-degree split point starts on contact, reducing drill walk without a center punch
• Straw finish indicates cobalt content and serves as a light oxidation barrier
• Regular spiral flutes promote efficient chip evacuation in through-hole drilling
• Straight cylindrical shank fits standard drill chucks without an adapter
• Heavy-duty grade rated for repeated use in demanding production and maintenance environments

Compatibility

Designed as a general-purpose replacement or stock drill bit for any application requiring a No. 20 wire gauge (0.1610 inch) hole in stainless steel or hardened materials, compatible with any drill press or hand drill equipped with a standard three-jaw chuck sized for a 0.1610-inch straight shank.

Installation Notes

Secure the shank fully in the chuck and verify concentricity before drilling. Use cutting fluid or coolant when drilling stainless steel to extend bit life and prevent work hardening at the cut face. Reduce feed pressure as the bit breaks through to avoid grabbing. Always wear eye protection and secure the workpiece before operation.
