Osg 6153011 Screw Machine Drill Bit 3mm Hss 2-flute

Product Description

The OSG 6153011 is a screw machine length drill bit designed for high-performance drilling in a wide range of metalworking applications. Built from high speed steel with a coated finish, this bit features a two-flute spiral configuration, a straight-cylindrical shank, and a four-facet point ground to a 130-degree angle. The web-thinned, tapered web design reduces thrust and improves chip evacuation at the cutting point. At 3.00 mm (0.1181 inches) in diameter, it is sized for precision work in screw machine and short-hole drilling operations. This bit belongs to OSG Series 1100 and is intended for use by machinists and tool-and-die professionals working in production or job-shop environments.

This drill bit is suited for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Its screw machine length profile — shorter than a jobber bit — provides increased rigidity and improved accuracy in drill press, turret lathe, CNC, and screw machine setups. The 5xD flute-to-diameter ratio supports efficient chip removal in moderate-depth holes. It is a practical choice for production runs where consistent hole quality and tool life in ferrous and non-ferrous materials are required.

Key Features

• High speed steel construction with coated finish for extended wear resistance
• Four-facet, 130-degree point angle for self-centering entry and reduced thrust
• Web-thinned tapered web improves chip flow and reduces cutting force
• Screw machine length body provides extra rigidity over jobber-length alternatives
• Two-flute spiral design handles steel, stainless steel, and aluminum workpieces
• Right-hand cut, straight-cylindrical shank for standard chuck compatibility

Compatibility

Designed as an OEM-style replacement screw machine length drill bit for use in standard drill chucks and collets accepting a 3.00 mm straight-cylindrical shank. Compatible with primary workpiece materials including steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate as stated by the manufacturer.

Installation Notes

Installation and use should be performed by qualified machinists or tooling professionals. Secure the shank fully in a properly sized drill chuck or collet before operation and confirm runout is within acceptable tolerances for the application. Inspect the cutting edges for wear or damage before each use and replace the bit if chipping or excessive dulling is observed. Follow applicable shop safety procedures and machine-specific operating guidelines when setting spindle speed and feed rate for the workpiece material.
