Hertel F.901.2381 Reduced Shank Drill Bit 15/16 in Hss

Product Description

The HERTEL F.901.2381 is a reduced shank twist drill bit designed for general-purpose drilling in metal, wood, and similar materials. It features a 15/16-inch (0.9375 inches) cutting diameter paired with a 3/4-inch straight-cylindrical shank, making it compatible with standard drill chucks without requiring a larger spindle bore. The 118-degree split-free point angle suits a wide range of common materials. The high-speed steel construction with an oxide finish provides adequate heat and wear resistance for production and maintenance drilling applications. Licensed machinists, maintenance technicians, and metalworking professionals are the primary users of this bit.

This drill bit is suited for general-purpose drilling operations in job shops, maintenance facilities, and manufacturing environments. The reduced shank design allows a 15/16-inch cutting diameter to be used in drill presses, mills, or hand drills equipped with a standard 3/4-inch chuck. With a 3-inch flute length and a maximum drilling depth of 3 inches, it handles typical through-hole and blind-hole operations in steel plate, aluminum, plastics, and similar workpiece materials.

Key Features

• 118-degree drill point angle for general-purpose use across common metals and materials
• High-speed steel construction provides durability under moderate heat and cutting loads
• Oxide finish reduces friction and offers light corrosion resistance during storage and use
• 3-inch flute length supports a maximum drilling depth of 3 inches
• 6-inch overall length with a 2-1/4-inch shank length for stable chuck engagement

Compatibility

Designed as a general-purpose reduced shank drill bit compatible with drill presses, milling machines, and hand drills fitted with a 3/4-inch or larger chuck capacity.

Installation Notes

Secure the 3/4-inch shank fully into the chuck before drilling and verify the chuck key is removed before starting the machine. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and reduce heat buildup. Do not exceed the recommended drilling depth of 3 inches; retract the bit periodically to clear chips and prevent binding. Inspect the cutting edges for wear before each use and replace the bit if chipping or dulling is observed.
