Cleveland C04697 Screw Machine Drill Bit 1-1/4 in Hss

Product Description

The CLEVELAND C04697 is a screw machine length (stub length) drill bit designed for high-volume drilling in metal fabrication, machining, and general industrial applications. Manufactured from high-speed steel with a bright/uncoated finish, this bit features a 1-1/4 inch diameter, a standard 118-degree point angle, and a 6-3/4 inch overall length. The shortened flute length relative to a jobber-length bit reduces deflection and improves rigidity, making it well-suited for use in drill presses, lathes, and CNC machinery where close-tolerance holes are required.

This bit is intended for use in metal-cutting applications including alloy steel and aluminum workpieces. Its straight cylindrical shank measures 1.0000 inch in diameter and 2-1/4 inches in length, compatible with standard drill chucks and collet-style toolholding systems. Series 2120 denotes Cleveland's general-purpose screw machine length line, built to ASME B94.11M standards. Machinists and tool-and-die tradespeople will find this bit appropriate for production drilling where stub-length rigidity is a priority over deep-hole reach.

Key Features

• 1-1/4 inch diameter with a diameter tolerance of +0.0000 to -0.0015 inches for consistent hole sizing
• 118-degree standard point angle for general-purpose metal cutting
• High-speed steel construction — suitable for alloy steel and aluminum workpieces
• Screw machine (short) length design reduces deflection and improves rigidity over jobber-length bits
• 2-flute right-hand spiral design with regular helix for efficient chip evacuation
• Bright/uncoated finish — no coating buildup to affect shank fit or hole diameter
• Conforms to ASME B94.11M and ANSI specification standards

Compatibility

Designed as a general-purpose screw machine length drill bit for use with drill presses, lathes, and machine tool setups that accept a 1.0000 inch straight cylindrical shank. Primary workpiece materials include alloy steel and aluminum as specified by the manufacturer.

Installation Notes

This bit should be installed by qualified machinists or toolroom personnel following standard machine tool lockout/tagout procedures before chuck or collet changes. Ensure the shank is fully seated and the chuck is tightened to the machine manufacturer's specification before engaging the spindle. Do not use this bit in handheld drill applications — the 1-1/4 inch diameter and stub-length geometry are intended for rigid machine tool setups only. Coolant-through is not supported on this bit; apply cutting fluid externally as required for the workpiece material.
