Precision Twist Drill 6000714 Jobber Drill Bit 4.40mm

Product Description

The PRECISION TWIST DRILL 6000714 is a 4.40 mm (0.1732 inch) cobalt high speed steel jobber-length drill bit designed for general-purpose drilling in steel and other metals. The 135-degree split point starts on contact without a center punch and reduces walking on hard surfaces. A straw oxide finish improves surface hardness and helps resist heat buildup during extended drilling cycles. The two-flute, right-hand spiral design evacuates chips efficiently and keeps the cut clean. With an overall length of 3-5/32 inches and a flute length of 1-27/32 inches, this bit fits standard drill chucks used in hand drills, drill presses, and CNC drilling operations.

This drill bit is intended for metal-working tradespeople, maintenance technicians, and fabricators who regularly drill into steel, cast iron, non-ferrous metals, and similar materials. The Series 2ACO designation places it in a heavy-duty performance tier suited to production and shop environments where consistent hole quality and tool life matter. The straight cylindrical shank accepts any standard keyless or keyed chuck sized for up to 4.40 mm. It conforms to DIN 338 and ANSI standards, making it a recognized drop-in match for equivalent jobber-length metric bits.

Key Features

• 4.40 mm diameter cobalt HSS construction for improved heat and wear resistance over standard HSS
• 135-degree split point reduces thrust force and eliminates the need for a center punch on most metals
• Straw oxide finish adds surface hardness and helps dissipate heat during continuous drilling
• Right-hand regular spiral flutes clear chips efficiently on through-hole and blind-hole applications
• Web-thinned, tapered web improves cutting efficiency and reduces drill breakage under load
• Conforms to DIN 338 and ANSI standards for consistent dimensional accuracy

Compatibility

Designed as a DIN 338 and ANSI jobber-length replacement drill bit suitable for steel, cast iron, non-ferrous metals, and similar workpiece materials designated under material codes P, M, K, N, and S.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists, fabricators, or maintenance technicians familiar with drilling equipment. Power down and secure the workpiece before inserting or removing the bit from the chuck. Verify chuck size matches the 4.40 mm straight shank before tightening. Use appropriate cutting fluid or lubricant for the workpiece material to extend tool life and maintain hole quality.
