Cleveland C04395 Screw Machine Drill Bit Wire 45 Hss

Product Description

The CLEVELAND C04395 is a screw machine length (stub) drill bit sized to wire gauge 45, with a decimal diameter of 0.0820 inches. It is ground from high-speed steel with a bright, uncoated finish and features a standard 118-degree split point with web thinning for easier entry and reduced thrust. The two-flute, right-hand spiral design provides efficient chip evacuation in short-hole applications. At 1.75 inches overall length, this bit is intended for use in screw machines, CNC lathes, drill presses, and turret setups where a compact tool is required. Licensed machinists, toolroom techs, and production line operators are the primary installers.

This bit is suited for general-purpose drilling in alloy steel and aluminum workpieces where close-tolerance hole sizing is needed. The stub length geometry reduces deflection and improves rigidity compared to jobber-length bits, making it a practical choice for tight-clearance fixtures and multi-spindle screw machine heads. The parallel web configuration supports consistent cutting geometry across the flute length. It meets ASME B94.11M standards for screw machine length drill bits.

Key Features

• 118-degree standard point angle with web thinning for reduced entry thrust
• High-speed steel construction with bright, uncoated finish for general-purpose use
• Stub screw machine length at 1.75 inches OAL reduces deflection in short-reach setups
• Right-hand cut, two-flute spiral design for efficient chip clearing
• Meets ASME B94.11M and ANSI specification requirements

Compatibility

Designed as a general-purpose screw machine length drill bit suitable for use in alloy steel and aluminum workpieces. Compatible with any standard straight-shank chuck or collet accepting a 0.0820-inch diameter shank. Series 2120.

Installation Notes

Install in a properly sized collet or drill chuck to the full shank depth before securing. Power down or lock out the machine spindle before changing tooling, following applicable OSHA lockout/tagout procedures. Inspect the cutting edges for chipping or wear before each use; resharpening is not recommended at this diameter. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole tolerance.
