Precision Twist Drill 6000622 Cobalt Jobber Drill 2.30mm

Product Description

The PRECISION TWIST DRILL 6000622 is a cobalt jobber-length drill bit designed for general-purpose drilling in steel and other ferrous and non-ferrous materials. It measures 2.30 mm (0.0906 inches) in diameter with an overall length of 2-3/32 inches (2.0938 inches). The 135-degree split point reduces walking at startup and lowers thrust load during entry. A straw oxide finish provides moderate lubricity and heat resistance. The web-thinned, tapered web construction improves chip evacuation and reduces cutting resistance. Licensed tradespeople and machinists working in production or maintenance applications are the primary users of this bit.

This drill bit is suited for drilling steel, cast iron, aluminum, and similar materials in both production and job-site settings. The regular spiral flute geometry handles standard chip loads without specialized coolant, as coolant-through is not supported in this design. The straight cylindrical shank seats in standard drill chucks without modification. It conforms to DIN 338 and ANSI standards, making it a compatible fit for most jobber-drill applications in light to heavy-duty drilling operations.

Key Features

• Cobalt construction for improved heat resistance and hardness retention in steel drilling
• 135-degree split point reduces bit walking and lowers entry thrust
• Straw oxide finish provides lubricity and mild corrosion resistance
• Web-thinned tapered web improves chip flow and reduces cutting force
• Right-hand cut, regular spiral flute for standard chip evacuation
• Meets DIN 338 and ANSI standards for jobber-length drill bits

Compatibility

Designed as an OEM-style jobber drill replacement conforming to DIN 338 and ANSI standards, compatible with any standard drill chuck accepting a 0.0906-inch straight cylindrical shank in the 2.00 mm to 3.00 mm diameter range.

Installation Notes

This drill bit is installed and used by machinists, maintenance technicians, and trade professionals operating drill presses, hand drills, or CNC equipment. Secure the straight shank firmly in the chuck before operation and verify chuck key removal prior to startup. Eye protection and appropriate work-holding should be in place per standard shop safety practice. Do not exceed the recommended drilling depth of 1.063 inches for optimal chip evacuation and bit longevity.
