Cleveland C11418 Cobalt Jobber Drill Bit Wire 18 135 Deg

Product Description

The CLEVELAND C11418 is a cobalt jobber-length drill bit designed for professionals who need reliable performance in tough materials. Manufactured from M42 cobalt high-speed steel and finished with a TiAlN coating, it handles cast iron, stainless steel, and other hard-to-drill workpieces that wear out standard HSS bits. The 135-degree split point reduces walking at startup and lowers thrust force needed to penetrate the material. With a parabolic flute geometry and web-thinned, tapered web configuration, chips evacuate efficiently even in deep-hole applications. Overall length is 3.25 inches, and the straight-cylindrical shank diameter is 0.1695 inches (Wire Size 18). This bit is a right-hand cut, two-flute design suited for use in drill presses, CNC machining centers, and handheld power drills.

This bit is intended for use in metal fabrication, maintenance and repair, and industrial production environments where stainless steel and cast iron are common workpiece materials. The TiAlN coating provides heat resistance at elevated cutting speeds, making the C11418 appropriate for production drilling where cycle times matter. Wire size 18 at 0.1695 inches decimal is a common size for close-tolerance pilot holes and clearance holes in sheet metal and structural components. Machinists, millwrights, and maintenance technicians are the primary installers and users of this bit.

Key Features

• M42 cobalt steel construction for heat and wear resistance in hard metals
• TiAlN coating extends tool life at elevated cutting temperatures
• 135-degree split point reduces thrust and eliminates center-punch requirement on most surfaces
• Parabolic flute with web-thinned tapered web promotes fast chip evacuation
• Right-hand cut, two-flute design compatible with standard drill chucks
• Straight-cylindrical shank fits standard 3-jaw chucks and collets
• Meets ASME B94.11M and DIN 338 standards

Compatibility

The C11418 is a Series 2075A jobber-length drill bit in Wire Size 18 (0.1695 inches), designed as a direct-fit replacement or upgrade for standard HSS jobber bits of the same diameter. Primary workpiece materials are cast iron and stainless steel. It fits any standard drill chuck or collet accepting a 0.1695-inch straight-cylindrical shank.

Installation Notes

Secure the shank fully in the drill chuck or collet before beginning any drilling operation. For best results in stainless steel, use cutting fluid and maintain steady feed pressure to avoid work-hardening the surface. Ensure the drill press or CNC spindle speed is appropriate for the workpiece material and bit diameter before engaging the cut. Inspect the cutting edges for wear or chipping before each use, as a damaged point reduces accuracy and can cause bit breakage.
