Osg 215-2610 Screw Machine Drill Bit 0.261 in Carbide

Product Description

The OSG 215-2610 is a screw machine length drill bit engineered for precision drilling in metalworking and machining applications. Built from solid carbide with a bright/uncoated finish, this bit delivers rigidity and wear resistance suited to demanding production environments. It features a 135-degree split point for fast, accurate engagement with minimal walking, and a slow spiral flute geometry that promotes efficient chip evacuation. The straight-cylindrical shank measures 0.261 inches in diameter for secure chuck retention. Machinists and toolroom professionals working with CNC equipment or manual drill presses will find this bit well suited to tight-tolerance work.

The 215-2610 is designed for screw machine length applications where a shorter overall length provides added rigidity compared to jobber-length bits. This geometry is commonly used when drilling through ferrous metals, non-ferrous alloys, and similar materials in production machining or fabrication shops. The solid carbide construction makes it appropriate for use in high-speed and rigid machine setups rather than handheld drilling operations.

Key Features

• Solid carbide construction for rigidity and extended tool life in production machining
• 135-degree standard point angle for self-centering entry and reduced thrust force
• Slow spiral flute configuration supports chip flow in screw machine length applications
• Bright/uncoated finish — no coating buildup to affect tolerances
• Tapered web configuration adds strength at the cutting tip
• Right-hand cut with straight-cylindrical shank for compatibility with standard drill chucks and collets

Compatibility

Designed as an OEM-style replacement and standard production drill bit for use in screw machines, CNC machining centers, and rigid drill press setups requiring a 0.261-inch diameter hole.

Installation Notes

This drill bit is intended for installation in machine spindles, collet chucks, or keyless chucks by qualified machinists or toolroom personnel. Ensure the machine is fully powered down and the spindle is secured before changing tooling. Solid carbide tooling requires a rigid, vibration-free setup — avoid use in handheld or flexible-arm drilling equipment where deflection can cause bit failure. Verify spindle speed and feed rate are appropriate for the workpiece material before beginning the cut.
