Hertel F.901.2064 Reduced Shank Drill Bit 13/16 in Hss

Product Description

The HERTEL F.901.2064 is a reduced shank twist drill bit designed for general-purpose metal drilling applications. It features a 13/16 inch (0.8125 inch) cutting diameter paired with a 3/4 inch straight-cylindrical shank, allowing it to fit standard drill chucks while cutting an oversized bore. The 118-degree split-free point angle suits a wide range of ferrous and non-ferrous materials. Constructed from high-speed steel with an oxide finish for added surface hardness and corrosion resistance, this bit delivers consistent performance in production and maintenance drilling environments. Licensed machinists, millwrights, and maintenance technicians are the primary users.

This drill bit is suited for general-purpose drilling in metal fabrication shops, maintenance facilities, and production environments where hole sizes larger than the available chuck capacity are required. The reduced shank design allows a standard 3/4 inch chuck to hold a bit that cuts a 13/16 inch hole, eliminating the need for a larger machine spindle. With a 3 inch flute length and a maximum recommended drilling depth of 3 inches, it handles through-holes and blind bores in mild steel, aluminum, and similar materials.

Key Features

• 13/16 inch cutting diameter with a reduced 3/4 inch straight-cylindrical shank for standard chuck compatibility
• 118-degree drill point angle for general-purpose performance across common metals
• High-speed steel construction provides heat resistance during sustained drilling cycles
• Oxide finish adds surface hardness and light corrosion protection
• 3 inch flute length supports chip evacuation and a maximum drilling depth of 3 inches
• 6 inch overall length with a 2-1/4 inch shank length for positive chuck engagement

Compatibility

Designed as a general-purpose reduced shank drill bit compatible with standard 3/4 inch keyed or keyless drill chucks on bench drills, drill presses, and similar machine tool spindles.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with drill press and machine tool operation. Secure the shank fully in the chuck before operation and verify the workpiece is properly fixtured or clamped. Always wear appropriate eye protection and ensure the machine is at a full stop before changing bits or clearing chips. Follow the machine manufacturer's recommended speed and feed guidelines for the material being drilled.
