Cleveland C04414 Screw Machine Drill Bit Wire 37 Hss

Product Description

The CLEVELAND C04414 is a screw machine length (stub-length) drill bit designed for high-volume drilling in close-clearance and production environments. Built from high-speed steel (HSS) with a bright/uncoated finish, it carries a wire gauge size of 37, equal to 0.1040 inches in decimal. The 118-degree standard point angle suits general-purpose drilling in a wide range of materials. The shortened overall length of 1-13/16 inches provides added rigidity compared to jobber-length bits, reducing deflection and improving hole accuracy. A straight-cylindrical shank allows direct chucking in standard drill presses, CNC machining centers, and hand drills. Diameter tolerance is held to +0.0000 to -0.0005 inches, meeting ASME B94.11M standards.

This bit is suited for production drilling, tapping pre-drill operations, and screw clearance holes in alloy steel and aluminum in both shop and field settings. The stub-length body limits overhang in turret and gang-drill setups, making it a common choice for machinists, tool-and-die workers, and maintenance technicians who need consistent results at small diameters. The two-flute spiral design with a web-thinned, parallel web construction promotes efficient chip evacuation and reduced thrust when drilling at production feed rates.

Key Features

• Wire size 37 (0.1040 inches) with diameter tolerance of +0.0000 to -0.0005 inches per ASME B94.11M
• High-speed steel construction — suitable for alloy steel and aluminum workpieces
• 118-degree standard point angle with web-thinned, parallel web for reduced thrust
• Screw machine (stub) length — 1-13/16 inches OAL for rigidity in close-clearance setups
• Bright/uncoated finish — easy to inspect for wear; no coating buildup in small-diameter holes
• Right-hand cut, two-flute spiral design with straight-cylindrical shank (0.1040 inches shank diameter)

Compatibility

Designed as a general-purpose screw machine length drill bit in the CLEVELAND Series 2120, suited for use in standard drill chucks, CNC turret setups, and gang-drill fixtures that accept straight-cylindrical shanks at the 0.1040-inch shank diameter.

Installation Notes

Secure the shank fully in the chuck or collet before operation to prevent runout at this small diameter. Ensure spindle speed and feed rate are appropriate for the workpiece material — high-speed steel bits in aluminum typically run at higher RPM than in alloy steel. Inspect the cutting edges and web for wear before each use; at wire-gauge diameters, even minor edge dulling increases the risk of bit breakage. No coolant-through capability is present on this bit; apply cutting fluid externally when drilling steel to extend tool life.
