Osg 8608119 Screw Machine Drill Bit 3/64 in Xpm

Product Description

The OSG 8608119 is a screw machine length drill bit designed for high-performance drilling in ferrous and hard materials. Measuring 3/64 inch (0.0469 inches, 1.19 mm) in diameter with a 130-degree drill point angle, this bit features an XPM high-performance coating applied over a straight-cylindrical shank. The compact screw machine length — 40.00 mm overall — positions this bit for use in tight-clearance applications where a jobber-length bit would not fit. X-thinned web geometry reduces thrust load and improves chip evacuation. Two spiral flutes with a regular helix and a tapered web configuration deliver clean entry and consistent hole quality in production drilling environments.

This bit is suited for drilling steel, alloy steel, cast iron, and nickel alloy workpieces in CNC machining centers, turret lathes, screw machines, and manual drill press setups. The short flute length — 8.00 mm — and rigid body make it well-suited for shallow-hole, high-cycle production work where runout control and tool life matter. Machinists, tool-and-die technicians, and CNC operators working in metalworking shops are the primary users of this Series 1900 bit.

Key Features

• XPM high-performance coating for extended tool life in ferrous materials
• 130-degree drill point angle optimized for hard and tough alloys
• X-thinned web reduces drilling thrust and improves chip flow
• Screw machine length body provides rigidity in tight-clearance setups
• Right-hand cut, two-flute spiral configuration for consistent chip evacuation
• Diameter tolerance of +0 to -0.014 mm for precise hole sizing

Compatibility

Designed for use in standard straight-shank drill chucks and collet holders; primary workpiece materials include steel, alloy steel, cast iron, and nickel alloy. Coolant-through is not supported on this bit.

Installation Notes

Install in a properly sized drill chuck or collet to the full shank depth before operation. Confirm spindle runout is within acceptable tolerance before beginning high-cycle production runs, as runout accelerates wear on small-diameter bits. Secure the workpiece firmly; do not apply side load to the bit shank. Inspect the cutting edges and web condition before each use and replace the bit at first sign of chipping or excessive wear.
