Chicago-latrobe 48714 Screw Machine Drill Bit 0.182 in Hss

Product Description

The CHICAGO-LATROBE 48714 is a screw machine length drill bit designed for high-volume, close-tolerance drilling in metalworking applications. Built from high speed steel with a bright/uncoated finish, this bit carries a 118-degree standard point angle and a web-thinned tip that reduces thrust and improves penetration on entry. The straight-cylindrical shank seats in standard drill chucks without modification. At 2-3/16 inches overall length and 1-1/8 inches of flute length, the stub-length body provides increased rigidity over jobber-length bits, reducing deflection during through-hole and blind-hole drilling in production environments.

This bit is suited for drilling cast iron, non-ferrous metals, and steel in production machining, maintenance, and fabrication settings. The shortened screw machine length makes it a practical choice for drill presses, CNC turret mills, and screw machines where tool clearance is limited. The regular spiral and parallel web configuration support consistent chip evacuation across the listed workpiece materials. Wire size 14 designation corresponds to 0.182 inches, placing it in the 0.1500 to 0.2000 inch diameter range of the Series 157 lineup. Sold individually, with a minimum order quantity of 12 units per order.

Key Features

• High speed steel construction for general-purpose metal drilling
• 118-degree standard point angle with web-thinned tip for reduced entry thrust
• Screw machine (stub) length body increases rigidity and minimizes deflection
• Right-hand cut with regular spiral flute for reliable chip clearance
• Bright/uncoated finish, coolant-through not available
• Diameter tolerance held to +0.0000 to -0.0007 inches per ISO standards

Compatibility

Designed as a general-purpose replacement or production-use screw machine drill bit for use on cast iron, non-ferrous metals, and steel workpieces. Compatible with any standard drill chuck or collet accepting a straight-cylindrical shank at 0.182 inches diameter.

Installation Notes

Installation and use of this bit is performed by machinists, tool-and-die professionals, and maintenance technicians. Secure the straight shank fully in the chuck before operation and verify runout before beginning a production run. Always wear appropriate eye protection and secure workpieces firmly before drilling. Inspect the cutting edges for wear before each use and replace bits showing chipping or heat discoloration to maintain hole tolerance.
