Cleveland C04517 Screw Machine Drill Bit 17/64 in Hss

Product Description

The CLEVELAND C04517 is a screw machine length drill bit designed for general-purpose metal drilling in production and repair environments. Built from high-speed steel with a bright/uncoated finish, this bit features a 17/64-inch diameter (0.2656 inches), a standard 118-degree point angle, and a right-hand cutting direction. The short overall length of 2-5/8 inches makes it well-suited for drill presses, CNC lathes, and turret operations where clearance is limited. Two spiral flutes with a regular helix promote chip evacuation and stable cutting action. Machinists, tool-and-die workers, and maintenance technicians install this type of bit in high-volume drilling applications where consistent sizing and durability are required.

This bit is appropriate for drilling alloy steel, aluminum, and similar workpiece materials in both shop and field settings. The screw machine length format is commonly specified when stub-length rigidity is needed without sacrificing the chip-clearing capacity of a jobber bit. The straight-cylindrical shank fits standard drill chucks across a wide range of machine tools. It conforms to ASME B94.11M and ANSI specification standards, making it a reliable choice for shops that require traceable tooling compliance. It ships as a single unit per package.

Key Features

• 17/64-inch diameter (0.2656 inches) with a tight tolerance of +0.0000 to -0.0010 inches for consistent hole sizing
• 118-degree standard point angle with web-thinned, parallel web configuration for easier starting and reduced thrust
• High-speed steel construction rated for general-purpose cutting in alloy steel and aluminum
• Short screw machine length (2-5/8 inches OAL) provides added rigidity in tight-clearance setups
• Right-hand cut with two regular-spiral flutes for efficient chip evacuation
• Meets ASME B94.11M and ANSI standards for dimensional accuracy and performance

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with any drill press, turret lathe, CNC machine, or hand drill equipped with a standard drill chuck sized for a 0.2656-inch straight-cylindrical shank. Suited for workpiece materials including alloy steel and aluminum.

Installation Notes

Installation and use of drill bits should be performed by qualified machinists or maintenance technicians familiar with proper chuck seating and machine guarding practices. Secure the shank fully in the chuck and verify concentricity before operation to avoid runout. Always wear appropriate eye protection and follow applicable shop safety standards when operating rotating tooling. Do not exceed the rated speed range for the workpiece material and bit diameter.
