Chicago-latrobe 47223 Jobber Drill Bit 1.00 Mm Hss

Product Description

The CHICAGO-LATROBE 47223 is a jobber-length twist drill bit designed for general-purpose hole drilling in metal and cast iron. Built from high speed steel with an oxide finish for added wear resistance, this bit features a 118-degree standard point angle and a web-thinned, tapered web configuration that reduces thrust and improves chip flow. The straight-cylindrical shank measures 0.0394 inches in diameter, and the overall length is 34.00 mm (approximately 1.34 inches). The two-flute, right-hand spiral design conforms to DIN 338 specifications, making it a reliable choice for production and maintenance drilling in both shop and field environments.

This bit is suited for drilling cast iron and steel in general-purpose machining, fabrication, and maintenance applications. The Series 150 designation places it in a standard jobber-length category, appropriate for drill press, CNC, and hand-drill use. With a flute length of 12.00 mm and a shank length of 22.00 mm, it is a compact, small-diameter option for close-tolerance work where a 1.00 mm entry hole is required. This bit is typically selected by machinists, millwrights, and maintenance technicians working with tight drill size increments in metric series.

Key Features

• High speed steel construction with oxide coating for corrosion and wear resistance
• 118-degree standard point angle for general-purpose drilling in ferrous metals
• Web-thinned, tapered web reduces entry thrust and improves chip evacuation
• DIN 338 compliant for consistent dimensional accuracy
• Right-hand, regular spiral flute for reliable chip clearance
• Straight-cylindrical shank fits standard drill chucks without modification

Compatibility

Designed as a general-purpose metric jobber drill conforming to DIN 338, suitable for use in standard drill presses, CNC machining centers, and handheld power drills equipped with chucks that accept a 0.0394-inch straight-cylindrical shank.

Installation Notes

This drill bit is installed and operated by machinists, millwrights, and maintenance technicians. Secure the straight shank firmly in a keyed or keyless chuck before starting the spindle. Always use appropriate cutting fluid or lubricant when drilling steel to extend bit life and maintain hole tolerance. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
