Chicago-latrobe 78482 Solid Carbide Spade Drill Bit 1/16 in

Product Description

The CHICAGO-LATROBE 78482 is a solid carbide spade drill bit designed for precise, small-diameter drilling in demanding materials. Built from uncoated solid carbide with a bright finish, it delivers the rigidity and wear resistance required when working with non-ferrous metals and stainless steel. The 118-degree point angle is a standard geometry suited for a wide range of drilling applications. With a 1/16-inch cutting diameter, 1.5-inch overall length, and a right-hand cutting direction, this bit is sized for tight-tolerance work where dimensional accuracy is critical. Drill bit diameter tolerance is held to +0.0000 to -0.0005 inches.

This drill bit is part of the Chicago-Latrobe Series 780 and is intended for use in machine shop, maintenance, and production drilling environments. It is well suited for applications involving non-ferrous metals and stainless steel where a high-hardness tool material is required to maintain cutting edge integrity. The 5/16-inch flute length and 1.188-inch shank length make it compatible with standard drill chucks and collets used in CNC machining centers, drill presses, and hand-operated precision drilling equipment. Machinists, toolroom technicians, and fabricators working with small-diameter holes will find this bit appropriate for their setups.

Key Features

• Solid carbide construction provides superior hardness and wear resistance compared to high-speed steel alternatives
• 118-degree point angle suits general-purpose drilling in non-ferrous metals and stainless steel
• Bright uncoated finish - no coating buildup that could affect tolerances in precision drilling
• Right-hand cutting direction compatible with standard spindle rotation
• Tight diameter tolerance of +0.0000 to -0.0005 inches for close-tolerance hole requirements
• Series 780 geometry optimized for small-diameter solid carbide performance

Compatibility

Designed for use with non-ferrous metals and stainless steel workpiece materials. Fits standard drill chucks and collets accepting a 1/16-inch shank diameter. Part of the Chicago-Latrobe Series 780 solid carbide drill line.

Installation Notes

This bit is intended for use by machinists and toolroom professionals operating drill presses, CNC machining centers, or precision hand drilling equipment. Ensure the workpiece is properly fixtured and the spindle speed is set appropriately for the material and diameter before operation. Solid carbide is brittle - avoid side loading, interrupted cuts at high feed rates, or dropping the bit, as chipping or fracture can result. Inspect the cutting edge before each use and replace if any chipping is observed.
