Cleveland C15097 Cobalt Screw Machine Drill Bit Size 7

Product Description

The CLEVELAND C15097 is a screw machine length drill bit designed for high-performance drilling in demanding shop and field applications. Built from M42 cobalt steel with a coated finish, this bit handles alloy steels, aluminum, and other hard-to-machine materials that would wear out standard high-speed steel tooling. The wire size 7 diameter measures 0.2010 inches, with an overall length of 2.25 inches and a straight-cylindrical shank of the same 0.2010-inch diameter. The 135-degree split point starts on contact without a center punch, reducing walking on hard surfaces and improving hole location accuracy.

This bit is suited for machine shop work, maintenance and repair operations, and production drilling on metalworking equipment such as drill presses, CNC machining centers, and hand-held power drills. Its screw machine length profile — shorter than jobber length — provides added rigidity in tight setups and chuck-heavy applications. The parabolic flute geometry improves chip evacuation, especially in deep holes, making it a practical choice for machinists and industrial maintenance techs working with alloy and aluminum stock on a regular basis.

Key Features

• M42 cobalt steel construction resists heat buildup when drilling alloy steel and aluminum
• 135-degree split point eliminates center-punch requirement and reduces drill walking
• Parabolic flute design accelerates chip evacuation in deep-hole drilling
• Web-thinned parallel web reduces cutting resistance and thrust load
• Screw machine length body adds rigidity compared to jobber-length bits
• Diameter tolerance held to +0.0000 to -0.0007 inches per ASME B94.11M

Compatibility

Designed as a screw machine length replacement or upgrade drill bit for wire size 7 applications falling in the 0.2000 to 0.2500-inch drill bit size range, compatible with standard straight-shank drill chucks on drill presses, CNC machines, and handheld power tools.

Installation Notes

Installation and use of this drill bit should be performed by machinists or qualified industrial maintenance personnel familiar with rotating tooling safety practices. Secure the straight-cylindrical shank fully in a properly sized drill chuck before operation and verify chuck key removal before powering the machine. Follow applicable ANSI and ASME tooling standards for spindle speed and feed rate selection based on workpiece material. Inspect the cutting edges for wear or chipping before each use and replace the bit if point geometry is compromised.
