Precision Twist Drill 6000695 3.75mm Cobalt Jobber Drill

Product Description

The PRECISION TWIST DRILL 6000695 is a 3.75 mm cobalt high-speed steel jobber-length drill bit designed for general-purpose drilling in steel and a range of other workpiece materials. The 135-degree split point reduces walking at startup and allows drilling without a center punch on most metal surfaces. An oxide and straw coating provides lubricity and surface protection during cutting operations. The straight cylindrical shank measures 3.75 mm in diameter and seats directly into standard drill chucks. With an overall length of 2.75 inches and a flute length of 1.53 inches, this bit fits the classic jobber-length profile used in hand-held and bench drilling applications.

This drill bit is suited for production and maintenance drilling in steel, cast iron, aluminum, non-ferrous metals, and certain specialty alloys, consistent with its P, M, K, N, and S material-group ratings. The web-thinned, tapered-web point geometry reduces thrust load, which is useful in hand drilling and lower-horsepower drill press applications. The right-hand spiral flute configuration evacuates chips away from the cutting zone efficiently. It conforms to DIN 338 and ANSI standards, making it a direct fit for shops and trades that specify dimensionally standardized tooling.

Key Features

• 3.75 mm (0.1476 inch) diameter cobalt HSS construction for heavy-duty drilling in steel and hard alloys
• 135-degree split point with web thinning reduces thrust and eliminates center-punch requirement on most metals
• Oxide and straw coating improves surface hardness and reduces friction at the cutting edge
• Right-hand regular spiral flute provides efficient chip evacuation during through-hole and blind-hole drilling
• DIN 338 and ANSI compliant straight cylindrical shank fits standard drill chucks without adapters
• Maximum drilling depth of 1.54 inches suits typical through-hole applications in sheet metal, bar stock, and structural sections

Compatibility

Designed as a DIN 338 and ANSI standard jobber-length drill bit compatible with any drill press, hand drill, or CNC machining center equipped with a standard chuck or collet sized for a 3.75 mm straight shank.

Installation Notes

Installation is performed by machinists, tool and die technicians, maintenance mechanics, and trade professionals using a standard keyed or keyless drill chuck. Secure the shank fully into the chuck and tighten before powering the machine. Use appropriate cutting fluid or coolant when drilling steel to extend tool life and prevent work hardening at the bore wall. Inspect the cutting edges for chipping or wear before each use and replace the bit if edge integrity is compromised.
