Value Collection C87753-1 5/16 in Jobber Drill Bit Hss

Product Description

The VALUE COLLECTION C87753-1 is a 5/16-inch high speed steel jobber drill bit designed for general-purpose metal drilling in trade and industrial applications. Built to M7 HSS material grade, this bit carries a black and gold oxide coating that reduces friction and extends service life. The 135-degree split point geometry promotes faster penetration and reduces walking on hard or smooth surfaces, eliminating the need for a center punch in most setups. Web thinning further reduces cutting resistance at the tip. Licensed trades and machinists alike rely on this style of bit for everyday drilling in steel, cast iron, aluminum, and similar materials.

This jobber-length bit is suited for use in hand drills, drill presses, and milling machines across residential, commercial, and light industrial jobsites. Its straight cylindrical shank accepts standard 3-jaw drill chucks without modification. The right-hand spiral flute design channels chips away from the cutting zone during operation, keeping the cut clean. It is a practical choice for HVAC techs drilling sheet metal, plumbers boring through framing or fittings, and electricians running conduit holes through steel brackets or enclosures.

Key Features

• M7 high speed steel construction rated for heavy-duty drilling in ferrous and non-ferrous metals
• 135-degree split point tip reduces walking and lowers entry force on hard materials
• Black and gold oxide coating minimizes friction and resists heat buildup
• Web-thinned tapered web reduces thrust required at the drill tip
• Right-hand regular spiral flute efficiently evacuates chips during drilling
• Straight cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as an OEM-style jobber drill bit for use in any standard drill chuck accepting a 5/16-inch straight shank, including hand drills, drill presses, and milling machine setups.

Installation Notes

Installation should be performed by qualified trades or experienced operators familiar with rotating tool safety. Secure the workpiece fully before drilling and ensure the chuck is tightened properly before operation. Use appropriate cutting fluid when drilling through hardened or thick steel stock to manage heat and extend bit life. Inspect the cutting edges before each use and replace the bit if the tip shows chipping, bluing from heat, or significant wear.
