Hertel F.924.2699 Reduced Shank Drill Bit Cobalt

Product Description

The HERTEL F.924.2699 is a reduced shank cobalt drill bit designed for drilling through hard and tough materials including stainless steel, alloy steel, cast iron, and other ferrous metals. The bit features a 1.0625-inch cutting diameter with a reduced 3/4-inch straight cylindrical shank, allowing it to be used in standard drill chucks that could not accommodate a full-size shank. The 135-degree split point reduces walking and thrust at startup, improving hole accuracy. A straw finish provides a base level of heat resistance during extended use. At 6 inches overall length with a 3-inch flute length, this bit is suited for moderate-depth through-hole and blind-hole work in production, fabrication, and maintenance environments.

This drill bit is used in metalworking, fabrication shops, maintenance facilities, and industrial production settings where large-diameter holes are required in hard metals. The reduced shank design makes it compatible with drill presses, magnetic drills, and hand-held drills equipped with 3/4-inch capacity chucks. It is a general-purpose bit appropriate for one-off jobs and repetitive drilling operations alike. Machinists, millwrights, pipefitters, and maintenance technicians are the primary users of this size and style of bit.

Key Features

• 1.0625-inch cutting diameter with a reduced 3/4-inch straight cylindrical shank for use in standard chuck sizes
• 135-degree split point reduces thrust and minimizes bit walking on entry
• Cobalt tool material provides heat resistance and hardness retention when drilling tough alloys
• Straw finish for baseline thermal protection during sustained drilling operations
• 3-inch flute length supports a maximum drilling depth of 3 inches
• 6-inch overall length with a 2.25-inch shank length for stable chuck engagement

Compatibility

Designed as a general-purpose reduced shank drill bit compatible with drill presses and drilling equipment fitted with 3/4-inch capacity chucks.

Installation Notes

This bit is installed and operated by machinists, millwrights, and maintenance technicians using drill presses or magnetic base drills. Secure the shank fully in the chuck and verify runout before drilling. Use cutting fluid appropriate for the workpiece material to extend bit life and maintain hole quality. Do not exceed the recommended drilling depth of 3 inches per the flute length specification.
