Cle-line C18059 Jobber Drill No 6 Hss 135 Degree

Product Description

The CLE-LINE C18059 is a No. 6 wire-size jobber-length drill bit designed for high-performance drilling in steel and cast iron. Built from high-speed steel (HSS) with a black and gold oxide coating, it measures 3.75 inches in overall length with a 2.5-inch flute length and a 0.2040-inch diameter. The 135-degree split point reduces walking and lowers feed pressure at the start of a cut. A tapered web with web thinning improves chip evacuation and reduces thrust load during through-hole drilling. This is a heavy-duty grade bit that meets ASME B94.11M and DIN 338 standards. Licensed tradespeople and machining professionals install it in standard drill chucks on handheld and bench-mounted drilling equipment.

The C18059 is built for ferrous material applications including mild steel and cast iron in both production and maintenance-repair-overhaul (MRO) environments. The straight cylindrical shank fits standard 3-jaw chucks without modification. The regular right-hand spiral flute handles general-purpose through-hole and blind-hole work in the 0.2000 to 0.2500 inch diameter range. It is suited for HVAC, plumbing, electrical, and general fabrication tasks where a reliable wire-gauge drill bit is needed on the job or in the shop.

Compatibility

Designed as an OEM-style replacement or direct-use jobber drill bit for standard 3-jaw drill chucks accepting a 0.2040-inch straight shank, suitable for steel and cast iron workpieces in the 0.2000 to 0.2500 inch drill size range.

Installation Notes

Install in a calibrated 3-jaw chuck and tighten with a chuck key before operation. Power down or unplug the drill press or handheld drill before changing bits. Wear appropriate eye protection and secure the workpiece before drilling. Do not exceed the drill press or tool manufacturer recommended speed for the material and bit diameter being used.
