Osg 8595244 Screw Machine Drill Bit 0.096 in Hss

Product Description

The OSG 8595244 is a screw machine length drill bit designed for high-performance metal drilling in demanding trade and industrial applications. Built from high speed steel with a coated finish, it features a 130-degree faceted drill point and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The straight-cylindrical shank measures 3.00 millimeters and the overall length is approximately 1.81 inches (46.00 millimeters). With a 0.096-inch diameter and a 5xD flute-to-diameter ratio, this bit delivers consistent performance in short-reach drilling setups where precision and tool life matter.

This bit is suited for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate in production and maintenance environments. The screw machine length format — shorter than a jobber drill — provides added rigidity and improved hole location accuracy on drill presses, CNC machines, and turret lathes. It is commonly used by machinists, maintenance technicians, and fabricators who require tight tolerance holes in metalwork. The 2-flute spiral design with regular spiral geometry handles a wide range of work materials effectively.

Key Features

• 0.096-inch (wire size No. 41) diameter with a tolerance of +0 to -0.014 millimeters for precise hole sizing
• 130-degree faceted drill point reduces walking and improves entry on hard metals
• Web-thinned, tapered web lowers cutting force and extends tool life
• High speed steel construction with coated finish resists heat and wear
• Screw machine length (5xD flute ratio) provides rigidity over standard jobber-length bits
• Right-hand cut, 2-flute spiral design compatible with standard drill chucks and toolholders

Compatibility

Designed as an OEM-style screw machine drill bit suitable for use in standard straight-shank drill chucks and collet holders accepting a 3.00-millimeter shank diameter. Rated for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpiece materials per OSG Series 1100 specifications.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotary cutting tools. Secure the shank fully in the drill chuck or collet before operation and verify that spindle speed and feed rate are appropriate for the workpiece material and bit diameter. Always power down and de-energize the machine before changing tooling. Do not exceed the rated cutting capacity or use the bit as a reamer or punch.
