Osg 8608462 Screw Machine Drill Bit 0.1819 in Xpm

Product Description

The OSG 8608462 is a screw machine length drill bit designed for high-performance drilling in ferrous and hard materials. Built from XPM high-speed steel with a coated finish, it features a 130-degree split point and right-hand spiral flute geometry that reduces walking and improves chip evacuation. At 0.1819 inches (wire size No. 14) in diameter, this stub-length bit offers increased rigidity compared to jobber-length drills, making it well suited for high-cycle production and precision hole work in CNC and manual machine tool setups.

This drill bit is intended for use in metal fabrication, machine shops, and production environments where tight tolerances and consistent hole quality are required. Primary workpiece materials include steel, alloy steel, cast iron, and nickel alloy. The straight-cylindrical shank and compact screw machine length body are compatible with standard drill chucks, collets, and quick-change toolholders used on drill presses, lathes, and machining centers. It is sold individually and suits both low-volume tool-room use and higher-volume production applications.

Key Features

• XPM high-speed steel construction with coated finish for extended tool life in ferrous materials
• 130-degree drill point angle with R-thinned web for reduced thrust and improved point stability
• Screw machine (stub) length body provides greater rigidity and reduced deflection versus jobber-length bits
• Right-hand cut, regular spiral flute geometry promotes efficient chip removal
• Straight-cylindrical shank fits standard chucks and collets without adapters
• Diameter tolerance of +0 to -0.018 mm supports consistent, repeatable hole sizing

Compatibility

Designed for drilling steel, alloy steel, cast iron, and nickel alloy workpieces. Fits standard drill chucks and collets accepting a 6 mm straight-cylindrical shank. Part of OSG Series 1900 screw machine length drills covering the 0.1500 to 0.2000 inch decimal inch size range.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with rotating cutting tools. Ensure the machine spindle is fully stopped and the tool is securely clamped before beginning any setup. Use appropriate cutting fluid or coolant for the workpiece material to maximize tool life, noting that this bit does not support coolant-through delivery. Inspect the cutting edges and web for wear or chipping before each use and replace the bit if damage is observed.
