Value Collection C87758-6 25/64 in Hss Jobber Drill Bit 6pk

Product Description

The VALUE COLLECTION C87758-6 is a 25/64 inch (0.3906 inch) diameter jobber-length drill bit manufactured from M7 high speed steel with a black and gold oxide coating. The 135-degree split point geometry reduces walking on contact and lowers the thrust required to start a hole, making it well suited for production drilling and repetitive-use applications. The web-thinned, tapered web design further reduces cutting resistance. This bit is rated as heavy duty grade and is sold in a pack of 6. It is installed and used by machinists, maintenance mechanics, and trade professionals working in metal fabrication, HVAC, plumbing, and electrical rough-in where consistent, accurate hole sizing is required.

This jobber drill bit is sized for through-hole and clearance-hole work in ferrous and non-ferrous metals, plastics, and composite materials. The 5-1/8 inch overall length and 3-3/4 inch flute length are consistent with standard jobber-series geometry, fitting most 3-jaw drill chucks on handheld drills, drill presses, and milling machines. The straight cylindrical shank measuring 25/64 inch in diameter seats securely in standard keyless and keyed chucks. The pack of 6 supports shop stock, tool crib replenishment, and job-site kitting.

Key Features

• M7 high speed steel construction provides good wear resistance and toughness in interrupted-cut and production-drilling conditions
• 135-degree split point starts on contact without center-punching and reduces thrust requirements
• Black and gold oxide coating (proprietary oxide and TiN-style finish) reduces friction and helps extend edge life
• Web-thinned tapered web lowers cutting resistance across the full flute length
• Right-hand cutting direction with regular spiral flute for standard forward drilling
• Straight cylindrical shank compatible with standard keyed and keyless drill chucks
• Pack of 6 units supports stock replenishment and multi-tech job kitting

Compatibility

Designed as an OEM-style jobber drill bit for use in any standard drill chuck accepting a straight cylindrical shank in the 25/64 inch diameter range, including handheld power drills, drill presses, and milling machine setups.

Installation Notes

Drill bits in this size range are typically installed and operated by machinists, maintenance mechanics, and licensed trade professionals. Secure the shank fully into the chuck and verify the bit is centered and locked before operation. Always wear appropriate eye protection and ensure the workpiece is clamped securely before drilling. Follow applicable OSHA and shop-safety guidelines for rotating cutting tools.
