Hertel F.924.3810 Reduced Shank Drill Bit 1.5in Cobalt

Product Description

The HERTEL F.924.3810 is a reduced shank drill bit engineered for general-purpose drilling in metal and other tough materials. Built from cobalt high-speed steel, this bit handles heat and wear better than standard HSS tooling, making it well suited for production drilling and demanding shop environments. The 135-degree split-point tip reduces walking and requires less thrust to start a hole. With a 1.5-inch cutting diameter and a 3/4-inch straight-cylindrical reduced shank, it fits standard drill chucks and machine spindles without requiring a large-bore collet. Installed by machinists, toolmakers, and maintenance technicians, this bit is a practical choice for drilling larger-diameter holes in steel, stainless, and cast iron.

This drill bit is designed for use in drill presses, milling machines, and heavy-duty hand-held drills equipped with a 3/4-inch chuck capacity. The reduced shank allows a larger cutting diameter to be held in a standard chuck, expanding capability without requiring specialized tooling. It is suited for general-purpose applications in fabrication shops, maintenance facilities, and manufacturing environments where repeated large-diameter drilling is required. The straw finish indicates a heat-treated cobalt construction appropriate for ferrous and non-ferrous materials.

Key Features

• Cobalt construction resists heat buildup during high-speed or interrupted cutting
• 135-degree split-point tip starts on contact and reduces drill walking
• Reduced shank diameter of 3/4 inches allows use in standard drill chucks
• 3-inch flute length with a maximum drilling depth of 3 inches
• Straw finish indicates heat-treated cobalt for extended tool life
• Straight-cylindrical shank provides secure, concentric chuck grip

Compatibility

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

Installation Notes

Installation is performed by machinists or maintenance technicians using a properly sized drill chuck or machine spindle. Ensure the machine is powered down and locked out before changing tooling. Secure the shank fully in the chuck and verify runout before beginning a cut. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and maintain hole quality.
