Osg 8599017 Screw Machine Drill Bit Size 51 Xpm

Product Description

The OSG 8599017 is a screw machine length drill bit engineered for high-performance drilling in metalworking applications. Built from XPM high-speed steel and finished with a V coating, this bit handles demanding materials including steel, alloy steel, cast iron, and nickel alloy. The 130-degree split point geometry reduces walking on entry and lowers thrust requirements. At 1.6535 inches overall length with a 0.0670-inch cutting diameter, this stub-length configuration is well suited for rigid setups where overhang must be minimized. Licensed machinists, tool-and-die technicians, and metalworking professionals are the primary users.

This bit is designed for CNC machining centers, drill presses, and manual lathes in production and job-shop environments. The screw machine length body keeps deflection low during short-hole drilling cycles. Its right-hand spiral flute evacuates chips efficiently in the ferrous and nickel-based alloys common to precision component manufacturing. The Series 1900 designation places it within OSG's recognized high-performance stub-drill lineup.

Key Features

• XPM high-speed steel construction for elevated heat and wear resistance in hard metals
• V coating reduces friction and extends tool life in ferrous workpieces
• 130-degree point angle with X-thinned web for reduced entry force and better self-centering
• Screw machine (stub) length minimizes deflection and improves hole straightness
• Right-hand, 2-flute regular spiral design for efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks and collets without modification

Compatibility

Designed as an OEM-style replacement and standard tooling selection for production drilling operations in steel, alloy steel, cast iron, and nickel alloy workpieces requiring a wire gauge size 51 drill.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with cutting tool safety practices. Secure the straight-cylindrical shank fully in a compatible drill chuck or collet before initiating any cut. Ensure spindle speed and feed rate are set per the material and coating manufacturer guidelines before engaging the workpiece. Inspect the cutting edge for wear or chipping before each use and remove the bit from service if damage is observed.
