Value Collection XGO-27/64 Jobber Drill Bit 27/64 in Hss

Product Description

The VALUE COLLECTION XGO-27/64 is a 27/64 inch (0.4219 inch decimal) high speed steel jobber drill bit designed for general-purpose drilling in steel and cast iron. The split-point tip at 135 degrees reduces walking and allows the bit to engage the workpiece without a center punch in most applications. A black and gold oxide finish provides basic lubricity and corrosion resistance. With an overall length of 5.375 inches and a regular spiral flute configuration, this bit is suited for production and maintenance drilling tasks performed by machinists, HVAC technicians, plumbers, and electricians who need a reliable, standard-geometry drill bit for metal fabrication and field work.

This jobber drill bit is sized for drilling into steel, cast iron, and similar ferrous materials in both shop and field environments. The straight cylindrical shank at 0.4219 inch diameter fits standard three-jaw drill chucks found on benchtop drill presses, magnetic base drills, and portable hand drills. The 9xD flute-to-diameter ratio and 3.9375 inch maximum drilling depth make it appropriate for through-hole and moderate-depth drilling operations in residential and light commercial applications.

Installation Notes

Installation and use of this drill bit should be performed by qualified tradespeople familiar with safe drilling practices on metallic materials. Secure the workpiece firmly before drilling and verify the chuck is tightened to the appropriate setting to prevent slippage. Use appropriate cutting fluid or coolant when drilling into ferrous metals to extend bit life and reduce heat buildup. Always wear appropriate eye protection and ensure the drill press or hand tool is powered down and de-energized before changing bits.
