Cleveland C71252 Jobber Length Drill Bit 4.7 Mm Hss

Product Description

The CLEVELAND C71252 is a jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastics. Manufactured from high speed steel with an oxide coating, it resists heat buildup and extends service life in production drilling applications. The bit measures 4.7 mm (0.1850 inches) in diameter with an overall length of 3.15 inches and a flute length of 1.85 inches. The 118-degree standard point angle suits a wide range of common materials. A web-thinned tip reduces thrust requirements and improves centering at the start of a cut. This bit is a staple in tool cribs and service vans for machinists, pipefitters, and general tradespeople who need a reliable metric-size drill on hand.

The C71252 is suited for light to medium-duty drilling in both shop and field environments. It is commonly used in fabrication, maintenance, and repair operations where a 4.7 mm metric hole is required. The straight-cylindrical shank seats in standard three-jaw drill chucks without adapters, making it compatible with corded and cordless drills, drill presses, and CNC turret machines. Series 2001G is manufactured to ASME B94.11M and DIN 338 standards, which define dimensional tolerances and performance criteria widely recognized across trade and industrial applications.

Key Features

• High speed steel construction with oxide finish for heat and wear resistance
• 118-degree standard point angle for general-purpose use across common materials
• Web-thinned, tapered-web tip reduces entry thrust and improves self-centering
• Right-hand spiral flute design evacuates chips efficiently during through-hole drilling
• Straight-cylindrical shank fits standard drill chucks without modification
• Manufactured to ASME B94.11M and DIN 338 dimensional standards

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard three-jaw chucks on hand drills, drill presses, and CNC turret equipment accepting straight-cylindrical shanks in the 0.1500 to 0.2000 inch diameter range.

Installation Notes

Installation is performed by machinists, maintenance technicians, and trade professionals familiar with rotary cutting tools. Secure the shank fully in the chuck and verify concentricity before beginning a cut. Use appropriate cutting fluid or coolant when drilling ferrous metals to extend tool life, unless the application prohibits it. Inspect the cutting edges and web-thinned tip for wear or chipping before each use and replace the bit if the edge geometry is compromised.
