Osg 215-0625 Solid Carbide Drill Bit 1/16 in 135 Deg

Product Description

The OSG 215-0625 is a solid carbide screw machine length drill bit designed for precision drilling in a wide range of metalworking applications. Measuring 0.0625 inches (1/16 inch) in diameter with a 135-degree split point, this bit delivers clean entry and reduced walking on hard and abrasive workpiece materials. The Series 215 features a slow spiral flute geometry and web-thinned, tapered web configuration that improves chip evacuation and reduces thrust during drilling. The bright/uncoated finish suits applications where coating-induced dimensional buildup is a concern. Machinists, tool-and-die professionals, and precision fabricators install this bit in CNC machines, drill presses, and manual lathes where tight tolerances and small-diameter holes are required.

This drill bit is rated for use in steel, alloy steel, stainless steel, cast iron, aluminum silicate, nickel alloy, titanium, and titanium alloy. Its screw machine length and straight-cylindrical shank make it a standard fit for quick-change toolholders and collet chucks in production and job-shop environments. The 5xD flute-to-diameter ratio and 5/8-inch flute length support controlled chip flow in deep small-diameter holes. General purpose performance classification makes it a dependable choice across varied production runs.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 135-degree drill point angle with web thinning reduces thrust and improves centering
• Slow spiral flute design optimized for chip control in steel and stainless steel
• Bright/uncoated finish maintains true dimensional accuracy at small diameters
• Straight-cylindrical shank fits standard collet chucks and quick-change holders
• Drill bit diameter tolerance of +0 to -0.013 mm for consistent hole quality

Compatibility

Rated for drilling steel, alloy steel, stainless steel, cast iron, aluminum silicate, nickel alloy, titanium, and titanium alloy. Straight-cylindrical shank is compatible with standard collet chucks, drill chucks, and toolholders accepting 1/16-inch shank diameters.

Installation Notes

Installation and operation should be performed by qualified machinists or tooling technicians familiar with small-diameter carbide tooling. Carbide is brittle - secure workpieces firmly and avoid side-loading or flexing the bit during operation, as this can cause breakage. Ensure spindle runout is minimized before use; excessive runout accelerates wear and increases breakage risk at this diameter. Follow machine manufacturer guidelines for feed rate and spindle speed when working with solid carbide tooling at small diameters.
