Value Collection C87758 Jobber Drill 25/64 in Hss

Product Description

The VALUE COLLECTION C87758 is a 25/64 inch diameter jobber-length drill bit designed for general-purpose drilling in metal, wood, and composite materials. Built from M7 high speed steel with a black and gold oxide coating, this bit is rated for heavy-duty use. The 135-degree split point reduces walking at startup and requires less downside pressure than a standard 118-degree point. Web thinning further reduces cutting resistance at the center. Right-hand spiral flutes clear chips efficiently through the 3.75-inch flute length. This bit is a standard tool for machinists, millwrights, and maintenance trades working with hand-held or bench-mounted drill presses.

The C87758 is suited for production and maintenance drilling applications where a jobber-length bit covers most standard hole depths. The straight cylindrical shank fits standard 3-jaw drill chucks on portable drills and drill presses. The 25/64 inch size is commonly used for clearance holes, bolt holes, and pre-drill operations in light to medium steel, aluminum, and plastics. The 5.125-inch overall length places it in the standard jobber category, balancing reach with rigidity.

Designed as a standard jobber drill bit for use in 3-jaw drill chucks accepting a 25/64 inch straight shank on portable drills, drill presses, and milling machines.

Installation Notes

Secure the shank fully in the drill chuck and confirm the chuck key is removed before operation. Use appropriate cutting fluid when drilling ferrous metals to extend bit life. Ensure workpieces are clamped securely before drilling. Inspect the cutting edges for wear or chipping before each use and replace the bit if the split point or cutting lips show damage.
