Precision Twist Drill 5968600 Stub Drill Bit Hss 3/16 Inch

Product Description

The PRECISION TWIST DRILL 5968600 is a high speed steel metric stub drill bit designed for precision drilling in demanding trade and industrial applications. Built to a 3/16 inch (0.1875 inch) diameter with a 62 mm overall length and a 26 mm flute length, this bit delivers controlled cutting depth up to 2.5XD. The 135-degree split point reduces walking and enables fast penetration without a center punch. Two spiral flutes evacuate chips efficiently, and the steam oxide finish provides added corrosion resistance and lubricity during dry drilling operations. Licensed machinists, maintenance technicians, and fabricators rely on this bit for consistent performance across a range of materials.

This stub drill bit is suited for short-hole drilling in tight spaces where a standard-length bit would be impractical. It is engineered for use in metals and composites including aluminum, cast iron, copper, magnesium, nickel, stainless steel, steel, synthetic materials, and titanium. The straight shank fits standard drill chucks found on bench drills, hand drills, and CNC machining centers. The short flute length increases rigidity and reduces deflection, making it a reliable choice for production environments and repair shops alike.

Key Features

• 135-degree split point reduces thrust and prevents bit walking on entry
• High speed steel construction handles ferrous and non-ferrous materials
• Steam oxide finish improves lubricity and corrosion resistance
• Short stub length increases rigidity and minimizes deflection
• Two spiral flutes provide efficient chip evacuation
• Straight shank compatible with standard drill chucks

Compatibility

Designed as a stub-length replacement drill bit for use in standard 3/16 inch drill chuck applications across bench, handheld, and CNC drilling setups.

Installation Notes

Install and remove drill bits only when the drill or machine is fully powered down and the chuck is stationary. Secure the straight shank firmly in the chuck and verify concentricity before operation. Use appropriate cutting fluid for hard or heat-sensitive materials such as stainless steel and titanium. Follow applicable OSHA and shop-safety guidelines for rotating tool use.
