Osg 215-1875 Solid Carbide Jobber Drill Bit 3/16 in

Product Description

The OSG 215-1875 is a solid carbide jobber-length drill bit designed for precision hole-making in demanding materials. Built from solid carbide with a bright uncoated finish, this bit features a 135-degree web-thinned point that reduces thrust on entry and improves self-centering in flat and curved surfaces. The slow spiral flute geometry promotes chip evacuation in deep cuts while maintaining rigidity in the cut. At 3/16 inches (4.76 mm) in diameter with a straight-cylindrical shank, it fits standard drill chucks and CNC toolholders. Trades and machinists working with tight tolerances rely on the plus 0 to minus 0.013 mm diameter tolerance for consistent, repeatable hole sizing.

This bit is suited for drilling operations in steel, alloy steel, stainless steel, cast iron, aluminum silicate, nickel alloy, titanium, and titanium alloy. It handles blind holes, cross holes, standard through-hole drilling, and self-centering applications. The general-purpose tool classification makes it a practical choice for job shops, maintenance operations, and production environments where a single reliable bit needs to move across a range of workpiece materials. The two-flute configuration balances chip clearance with core strength at this diameter.

Key Features

• Solid carbide construction for hardness and wear resistance in ferrous and exotic alloys
• 135-degree web-thinned point reduces entry thrust and improves self-centering
• Slow spiral flute design aids chip control in deep and interrupted cuts
• Bright uncoated finish suitable for use with or without cutting fluid
• Straight-cylindrical shank fits standard drill chucks and collet holders
• Diameter tolerance of plus 0 to minus 0.013 mm for consistent hole sizing

Compatibility

Designed for use in steel, alloy steel, stainless steel, cast iron, aluminum silicate, nickel alloy, titanium, and titanium alloy workpieces. Compatible with standard drill chucks and CNC collet systems accepting a straight-cylindrical shank at 3/16 inches diameter. Suited for bench drill presses, machining centers, and handheld drill applications within appropriate speed and feed parameters for carbide tooling.

Installation Notes

Installation and use of solid carbide drill bits should be performed by qualified machinists or tooling technicians familiar with carbide tooling requirements. Ensure the workpiece is securely fixtured and the spindle is confirmed at the correct speed and feed for carbide before engaging the cut — carbide is brittle and susceptible to chipping under improper load or interrupted contact. Do not use with excessive runout in the chuck or collet, as lateral deflection will cause premature breakage. Cutting fluid is recommended for stainless steel, nickel alloy, and titanium to manage heat buildup.
