Osg 570018711 Solid Carbide Screw Machine Drill Bit 3/16

Product Description

The OSG 570018711 is a solid carbide screw machine length drill bit designed for high-performance drilling in steel, alloy steel, and cast iron. Built to Series 5700 standards, it features a 0.1875 inch (3/16 inch) diameter, a 180-degree flat drill point, and a web-thinned, tapered web configuration that reduces thrust and improves chip flow. The straight-cylindrical shank seats securely in standard drill chucks and machine tool holders. With a 2xD flute-to-diameter ratio and a coated finish, this bit is suited for production environments where tool life and hole quality matter.

This drill bit is intended for use in screw machine operations, CNC drilling, and general machining applications where a compact, stubby tool length improves rigidity and reduces deflection. Primary workpiece materials include steel, alloy steel, and cast iron. The right-hand cut with regular spiral flutes handles standard through-hole and blind-hole drilling in metalworking shops, job shops, and maintenance facilities. It is sold individually and is well suited for toolroom inventory or line production use.

Key Features

• Solid carbide construction for extended tool life in ferrous materials
• 180-degree flat drill point eliminates the need for a center punch on many applications
• Web-thinned, tapered web reduces cutting force and improves chip evacuation
• Coated finish enhances wear resistance and reduces friction during cutting
• Screw machine length (stubby) body increases rigidity and reduces runout
• Straight-cylindrical shank compatible with standard collets and drill chucks

Compatibility

Designed for use in screw machines, CNC machining centers, and drill presses working with steel, alloy steel, and cast iron workpieces. Compatible with standard straight-shank toolholders and collet chucks sized for 0.1875 inch shanks.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Secure the shank to the full recommended engagement depth in the collet or chuck before operation. Follow applicable shop safety standards and machine manufacturer guidelines for speeds and feeds when drilling ferrous materials with solid carbide tooling.
