Feature

●1-3/4-inches (45mm) Long; Sizes 1/4-inch (6.5mm), 5/16-inch (8mm) and 3/8-inch (10mm); Each drill bit has permanently etched size markings
●Non-slip special centering nib design with flat shaft for sure grip; pilot tip design increases accuracy and prevents slipping when held down for marking purposes.
●Unlike pilot bits that drill through both surfaces, these bits are easy to control while cutting without penetrating the lower surface
●Titanium coating offers a smooth drilling experience that prevents dulling from overheating for extended performance.
●Use this spot weld drill bit to separate spot welds and resistance spot welding panels without distorting the sheet metal.Great for removing welding spot or drilling metal sheets


Description

[PRECISE]: pilot tip design increases accuracy and prevents slipping when held down for marking purposes.

[HEAVY DUTY]: Special grade high speed steel cobalt mix is designed for long service life to withstand quick speed running rate.

[PRO GRADE]: Flat ground surface on bottom half of bit provides additional strength and chuck hold on any welding drill.

[APPLICATION]: Use this spot weld drill bit to separate spot welds and resistance spot welding panels without distorting the sheet metal.

[DURABLE]: Heat resistant titanium coating withstands high-performance metal and wood drilling when used in high temperature environments.
