Osg 10093505 Screw Machine Drill Bit 0.0935 in Cobalt

Product Description

The OSG 10093505 is a screw machine length drill bit designed for high-performance drilling in steel and alloy steel applications. Built from cobalt high speed steel with a coated finish, it delivers extended tool life and heat resistance in demanding production environments. The bit features a 130-degree drill point angle with X-thinned web geometry for improved penetration and reduced thrust force. At 0.0935 inches (wire size 42) in diameter and 1.97 inches overall length, this stub-length bit is suited for CNC machining centers, drill presses, and screw machine operations where rigidity and precision are required.

This drill bit is intended for metalworking professionals and machinists working primarily with steel and alloy steel. The screw machine (stub) length format provides increased rigidity over jobber-length bits, making it a practical choice for tight setups, short-reach drilling operations, and high-cycle production runs. The right-hand spiral flute design clears chips efficiently during through-hole and blind-hole drilling in ferrous materials.

Key Features

• Cobalt high speed steel construction for heat resistance and extended tool life in steel and alloy steel
• 130-degree drill point angle for aggressive cutting and reduced walking on entry
• X-thinned, tapered web configuration reduces thrust and improves chip evacuation
• Screw machine (stub) length at approximately 1.97 inches overall for maximum rigidity
• Straight-cylindrical shank at 0.125 inches diameter fits standard drill chucks and collets
• 2-flute regular spiral design with 3xD flute-to-diameter ratio for consistent chip flow

Compatibility

Designed as an OEM-style replacement or direct-use screw machine length drill bit for metalworking applications in steel and alloy steel, fitting any drill chuck or collet system that accepts a 0.125-inch straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or tool-and-die professionals familiar with metal cutting operations. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable tolerance. Power down and de-energize the machine spindle completely before changing or inspecting the bit. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection when drilling ferrous materials.
