Osg 8608437 Screw Machine Drill Bit 11/64 Inch Xpm

Product Description

The OSG 8608437 is a screw machine length drill bit engineered for high-performance drilling in ferrous and hard materials. Built from XPM high-speed steel with a V coating, it delivers increased wear resistance and longer tool life compared to standard HSS bits. The 130-degree split point reduces walking and allows immediate penetration without a center punch. With an overall length of 2.68 inches and a straight-cylindrical shank diameter of 0.2362 inches, this short-length bit is designed for rigid setups in drill presses, CNC machines, and screw machine operations where stub rigidity reduces deflection and improves hole accuracy.

This bit is suited for production drilling in steel, alloy steel, cast iron, and nickel alloys. Its screw machine length profile makes it a practical choice for tight-clearance drilling stations, turret lathes, and automatic screw machines where a standard-length bit would lack the required rigidity. It is also used in manual and CNC drill press operations where controlled chip evacuation and consistent hole tolerance are priorities. The 3xD flute-to-diameter ratio supports efficient chip removal in short-hole applications.

Key Features

• XPM high-performance high-speed steel construction for extended tool life in hard materials
• V coating increases surface hardness and reduces friction during cutting
• 130-degree standard point with R-thinned web reduces thrust and eliminates drill walk
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Screw machine length (3xD) provides maximum rigidity and minimizes deflection
• Right-hand spiral flute with tapered web for consistent chip evacuation

Compatibility

Designed for drilling in steel, alloy steel, cast iron, and nickel alloy workpieces. OSG Series 1900 screw machine drill bit compatible with standard straight-shank drill chucks and collet systems accepting a 6 mm (0.2362 inch) shank diameter.

Installation Notes

Installation and operation should be performed by a qualified machinist or tooling technician. Secure the shank fully in the chuck or collet and verify runout before beginning a cut. Always set spindle speed and feed rate appropriate to the workpiece material and bit diameter before engaging the cut. Inspect the cutting edges and coating for wear or chipping before each use and replace the bit if the point geometry is compromised.
