Cleveland C71229 Jobber Length Drill Bit 2.45 Mm Hss

Product Description

The CLEVELAND C71229 is a jobber-length twist drill bit designed for general-purpose drilling in metal, plastic, and similar materials. It measures 2.45 mm (0.0964 inches) in diameter with an overall length of 2.244 inches and a flute length of 1.181 inches. The bit is manufactured from high speed steel with an oxide coating that provides basic lubricity and surface protection during cutting. A standard 118-degree point angle and web-thinned tip reduce entry force and improve centering on most common workpiece materials. Licensed machinists, maintenance mechanics, and tool-and-die technicians are the primary users of this bit in production and field applications.

The C71229 is suited for general-purpose drilling operations in light to medium production environments. Its straight-cylindrical shank seats directly in standard drill chucks on benchtop drill presses, hand drills, and CNC drilling machines. The 2-flute spiral configuration with regular spiral type provides adequate chip evacuation for through-hole and blind-hole work in ferrous and non-ferrous materials. The Series 2001G designation places this bit within a standardized metric jobber-length family built to ASME B94.11M and DIN 338 specifications.

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard drill chuck accepting a straight-cylindrical shank in the 2.00 mm to 3.00 mm diameter range.

Installation Notes

Secure the shank fully in the drill chuck and confirm runout before beginning a cut. Power down and de-energize any machine tool before changing bits. Standard HSS bits are not rated for use in hardened steel without appropriate cutting fluid or reduced feed rates. Dispose of worn bits per applicable shop safety protocols.
