Chicago-latrobe 70123 Jobber Drill Bit Size 23 Hss Tin

Product Description

The CHICAGO-LATROBE 70123 is a jobber length twist drill bit designed for general-purpose drilling in metalworking applications. Built from high speed steel (HSS) with a titanium nitride (TiN) coating, it carries a wire gauge size of 23, corresponding to a decimal diameter of 0.1540 inches. The 118-degree standard point angle and web-thinned tip promote clean entry and reduce walking on hard surfaces. Overall length is 3-1/8 inches with a 2-inch spiral flute length. The straight-cylindrical shank seats securely in standard drill chucks. This bit is suited for use by machinists, maintenance technicians, and trade professionals working with cast iron and steel stock.

The CHICAGO-LATROBE 70123 fits into general shop, field service, and production drilling workflows where a compact, sub-quarter-inch HSS bit is needed. Primary workpiece materials listed by the manufacturer are cast iron and steel. The regular spiral flute and tapered web geometry handle a range of hole depths within the jobber length format. It is a single-piece, individually packaged unit conforming to DIN 338 standards, making it a straightforward replacement or replenishment buy for any toolcrib stocked to that specification.

Compatibility

Designed as a general-purpose jobber length drill bit conforming to DIN 338, suitable for use in any standard drill press, hand drill, or CNC setup accepting a straight-cylindrical shank of 0.1540 inches. Primary listed workpiece materials are cast iron and steel.

Installation Notes

Install and remove drill bits only after the drill press or power tool has been fully de-energized and the spindle has come to a complete stop. Secure the straight-cylindrical shank firmly in a properly sized chuck to prevent slippage and runout. Use appropriate cutting fluid or coolant for the workpiece material when drilling steel to manage heat buildup, keeping in mind this bit is not designed for coolant-through delivery. Eye protection and compliance with applicable OSHA and shop-safety requirements apply whenever rotary cutting tools are in use.
