Chicago-latrobe 47246 Jobber Drill Bit 2.15mm Hss

Product Description

The CHICAGO-LATROBE 47246 is a jobber-length twist drill bit designed for general-purpose drilling in metalworking applications. Built from high speed steel with an oxide coating, this bit measures 2.15 mm (0.0846 inches) in diameter with an overall length of 53 mm (2.087 inches). The standard 118-degree point angle and regular spiral flute geometry suit a wide range of production and maintenance drilling tasks. Web thinning reduces thrust load at the point, making starts cleaner in harder materials. A straight-cylindrical shank seats securely in standard drill chucks without slipping under load.

This bit is suited for drilling cast iron and steel in both shop and field environments. It fits into light-duty drill presses, hand drills, and CNC setups where a small-diameter jobber-length bit is called for. The Series 150 designation follows DIN 338 standards, making it a recognized specification among machinists and maintenance trades who need consistent tolerances across bit inventory. Diameter tolerance is held to -0.0005 to 0.0000 inches for precise hole sizing.

Key Features

• High speed steel construction with oxide coating for improved surface hardness and corrosion resistance
• 118-degree standard point angle for general-purpose drilling in cast iron and steel
• Web-thinned tapered web reduces cutting thrust and improves chip evacuation
• Right-hand cut, regular spiral flute with two flutes for efficient chip removal
• Straight-cylindrical shank compatible with standard drill chucks
• Meets DIN 338 specification for consistent dimensional tolerances

Compatibility

Designed as a general-purpose jobber-length drill bit per DIN 338 for use in standard three-jaw drill chucks and collet systems accommodating a 0.0846-inch straight shank diameter. Primary workpiece materials are cast iron and steel.

Installation Notes

Installation and use should be performed by machinists, maintenance technicians, or qualified tradespeople familiar with metal drilling practices. Secure the shank fully in the chuck and verify chuck key is removed before powering the drill. Use appropriate cutting fluid or coolant for extended runs in steel to prevent heat buildup. Follow applicable shop safety standards and wear eye protection during all drilling operations.
