Value Collection 01198530 Cobalt Jobber Drill No. 53

Product Description

The VALUE COLLECTION 01198530 is a cobalt jobber-length drill bit sized to wire gauge No. 53 (0.0595 inches) for use in metalworking and fabrication applications. Built from heavy-duty cobalt steel with a 135-degree split point, it starts on contact without a center punch and reduces walking on hard surfaces. The straw finish indicates the cobalt alloy content. At 1.875 inches overall length with a 0.875-inch flute, this is a compact, precise bit suited for through-hole and pilot-hole work in tight quarters. Licensed machinists, tool-and-die technicians, and maintenance mechanics are the typical installers.

This drill bit is designed for cutting stainless steel, hardened materials, and other tough ferrous and non-ferrous metals where standard high-speed steel bits lose hardness from heat. The 135-degree split point geometry is especially effective on work-hardening alloys such as 304 and 316 stainless. The right-hand, regular spiral flute evacuates chips efficiently on short-reach drilling. Its straight cylindrical shank fits standard drill chucks and collet holders without modification.

Key Features

• Cobalt steel construction retains hardness at elevated cutting temperatures
• 135-degree split point self-centers and reduces drill walk without a pilot hole
• Right-hand regular spiral flute for efficient chip evacuation
• No. 53 wire gauge size — 0.0595 inches decimal equivalent
• Straight cylindrical shank fits standard drill chucks and collet systems
• Rated for stainless steel and hardened materials

Compatibility

Designed as a standard wire-gauge jobber drill for use in any drill press, hand drill, or CNC drilling application that accepts a straight cylindrical shank at 0.0595 inches diameter.

Installation Notes

Install in a properly rated drill chuck or collet and confirm the shank is fully seated before operation. Use cutting fluid or coolant when drilling stainless steel or hardened materials to extend bit life and prevent work hardening at the cut face. Secure the workpiece firmly before drilling to prevent rotation. Inspect the cutting edges before each use and replace the bit if chipping or heat discoloration at the tip is observed.
