Osg 8608206 Screw Machine Drill Bit Size 46 Xpm

Product Description

The OSG 8608206 is a screw machine length drill bit designed for high-performance drilling in ferrous and hard materials. Built from XPM high-performance tool steel with a V coating, it delivers extended tool life in demanding production environments. The bit is sized at wire gauge 46 (0.0810 decimal inch / 2.06 mm) with a 130-degree point angle for aggressive entry into steel, alloy steel, cast iron, and nickel alloys. The overall length is 44 mm (1.73 inches) with a 3 mm (0.12 inch) straight-cylindrical shank. Right-hand cut, spiral flute geometry with X-thinned web reduces thrust and improves chip evacuation.

This drill bit is suited for screw machine operations, CNC drilling, and production drilling applications where short flute length and rigid stub geometry improve accuracy and reduce deflection. The screw machine length format makes it a standard choice on automatic screw machines, turret lathes, and machining centers targeting small-diameter hole work in steel and hard alloy components. Primary workpiece materials include steel, alloy steel, cast iron, and nickel alloys. The 3xD flute-to-diameter ratio is appropriate for shallow-to-moderate depth holes.

Key Features

• XPM high-performance tool steel construction with V coating for extended wear resistance
• 130-degree split point with X-thinned web reduces thrust and improves self-centering
• Wire gauge size 46 — 2.06 mm / 0.0810 inch diameter with tight tolerance of +0 to -0.014 mm
• Screw machine (stub) length at 44 mm OAL minimizes deflection in short-reach setups
• Regular spiral flute with tapered web configuration promotes chip flow in ferrous materials
• Right-hand cut, straight-cylindrical shank for standard drill chuck and collet compatibility

Compatibility

Designed for drilling steel, alloy steel, cast iron, and nickel alloy workpieces. Fits standard drill chucks and collets accepting a 3 mm (0.12 inch) straight-cylindrical shank. Part of OSG Series 1900.

Installation Notes

Installation and operation should be performed by qualified machinists or tooling technicians. Secure the shank fully in the drill chuck or collet before operation and verify runout before production use. Power down the machine and lock out energy sources before changing tooling. Do not exceed the recommended speed and feed parameters for the workpiece material and machine type — consult OSG cutting data tables for Series 1900 application guidance.
