Hertel F.901.4445 Reduced Shank Drill Bit 1.75in Hss

Product Description

The HERTEL F.901.4445 is a reduced shank drill bit engineered for general-purpose hole-making in metal, wood, and similar materials. It features a 1.75-inch cutting diameter paired with a 3/4-inch straight-cylindrical shank, allowing it to be chucked in standard drill presses and machine tool spindles that cannot accommodate a full 1.75-inch shank. Manufactured from high-speed steel with an oxide finish, the bit delivers solid wear resistance across a broad range of workpiece materials. The 118-degree drill point angle is the standard geometry for general-purpose drilling, providing a balance of cutting efficiency and point stability. At 3 pounds, the tool is built for machine use rather than handheld operation.

This bit is suited for production and maintenance drilling applications in shops, industrial facilities, and mechanical trade environments. It is typically run on a drill press, radial arm drill, or milling machine. The 3-inch flute length supports chip evacuation in moderate-depth holes, and the 2.25-inch shank length provides secure gripping purchase in the machine chuck. The 6-inch overall length keeps deflection manageable at this diameter. It is a practical choice for machinists, maintenance mechanics, and tool-and-die tradespeople who require a large-diameter drill in a reduced-shank format.

Key Features

• 1.75-inch cutting diameter with a 3/4-inch reduced straight-cylindrical shank for standard chuck compatibility
• 118-degree drill point angle for general-purpose performance across common workpiece materials
• High-speed steel construction provides heat and wear resistance under sustained cutting loads
• Oxide finish helps reduce friction and provides a baseline level of corrosion resistance
• 3-inch flute length supports chip clearance in holes up to 3 inches deep
• 6-inch overall length balances rigidity and reach for machine-mounted use

Compatibility

Designed as a general-purpose reduced shank drill bit compatible with drill presses and machine tool spindles fitted with a 3/4-inch capacity chuck or collet.

Installation Notes

Installation is performed by a machinist or qualified maintenance mechanic. Ensure the drill press or machine spindle is fully powered down and the chuck key is removed before securing or removing the bit. Clamp workpieces securely to the table before initiating a cut at this diameter. Use cutting fluid appropriate for the workpiece material to manage heat buildup and extend tool life.
