Cle-line C18056 Jobber Drill Bit Wire 3 Hss 135 Split Point

Product Description

The CLE-LINE C18056 is a jobber-length drill bit in wire gauge size 3 (0.2130 inches), manufactured from high speed steel with a gold oxide coating. It features a 135-degree split point for fast engagement and reduced walking on entry, and a web-thinned, tapered web configuration that lowers thrust requirements in harder materials. Overall length is 3.75 inches with a 2.5-inch spiral flute. The straight-cylindrical shank fits standard three-jaw chucks. This bit is rated for heavy-duty performance and suits production drilling environments where consistent hole quality in steel and cast iron is required.

The C18056 is designed for right-hand cutting in primary workpiece materials including cast iron and steel. The regular spiral flute evacuates chips efficiently during through-hole and blind-hole drilling operations. With a shank diameter of 0.2130 inches and a shank length of 1.25 inches, it seats securely in standard drill chucks used in machine shop, maintenance, and fabrication settings. The Series 1878 designation identifies this as a standard jobber-length geometry conforming to ASME B94.11M and DIN 338. Coolant-through is not available on this bit.

Key Features

• Wire size 3 diameter at 0.2130 inches with a tight tolerance of +0.0000 to -0.0007 inches
• 135-degree split point reduces walking and lowers entry thrust
• Web-thinned tapered web for reduced cutting resistance in hard metals
• Gold oxide coating improves lubricity and extends tool life in steel and cast iron
• Regular spiral flute with right-hand cut for standard chuck-mounted drilling
• Meets ASME B94.11M and DIN 338 standards for jobber-length geometry

Compatibility

Designed as a heavy-duty jobber-length replacement or production drill bit for use in cast iron and steel applications, conforming to ASME B94.11M and DIN 338 jobber-length standards.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard three-jaw drill chuck on a drill press, lathe tailstock, or handheld power drill. Secure the straight-cylindrical shank fully into the chuck before operation and verify runout before drilling critical holes. Always wear eye protection and ensure the workpiece is clamped or fixtured before engaging the spindle. Do not exceed the recommended feed and speed parameters for the workpiece material class.
