Hertel F.924.2461 Reduced Shank Drill Bit 31/32 in Cobalt

Product Description

The HERTEL F.924.2461 is a reduced shank cobalt drill bit designed for high-performance drilling in tough materials. The bit measures 31/32 inches (0.9688 inches) in diameter with a 3/4-inch straight cylindrical shank, making it compatible with standard drill chucks without requiring a full-shank bore. The 135-degree split point reduces walking at startup and allows penetration without a center punch in most applications. At 6 inches overall length with a 3-inch flute length, it provides reach and chip clearance suited to general-purpose production and maintenance drilling tasks. Licensed machinists, tool-and-die technicians, and millwrights are the primary installers of this bit class.

This bit is suited to general-purpose drilling in steel, stainless steel, cast iron, and other ferrous materials where cobalt construction provides the heat resistance necessary to maintain cutting edge integrity at higher feed rates and spindle speeds. The straw finish indicates a heat-treated cobalt steel substrate. It is appropriate for both production floor and job-site use in CNC drill presses, hand-held magnetic drills, and radial arm drill presses. The reduced shank design allows the 31/32-inch diameter to be chucked in a standard 3/4-inch capacity chuck.

Key Features

• Cobalt steel construction resists heat buildup during high-speed drilling in ferrous metals
• 135-degree split point reduces thrust force and eliminates center-punch step in most setups
• Reduced 3/4-inch straight cylindrical shank fits standard drill chucks
• 3-inch flute length provides chip evacuation up to 3 inches maximum drilling depth
• Straw finish indicates heat-treated cobalt substrate for extended tool life
• 6-inch overall length suits deep-reach and clearance-limited drilling applications

Compatibility

Designed as an OEM-style general-purpose reduced shank drill bit for use in any drill press, magnetic drill, or hand drill with a 3/4-inch or larger chuck capacity.

Installation Notes

Installation is performed by qualified machinists or maintenance technicians. Secure the shank fully in the chuck and verify runout before engaging the workpiece. Power down and lock out the drill press or magnetic drill base before changing bits. Do not exceed the rated cutting speed for the material being drilled, and apply cutting fluid when drilling stainless or hardened steel to extend tool life.
