JET 670502 Socket, 1/4 in, 4 mm Regular Socket, 6 Points

• Super premium 118 deg split point drill bits - bronze oxide (gold) finish
• Made from heavy duty high molybdenum, hardened steel for increased consistency and greater wear resistance
• Flutes are ground to extremely tight tolerances for increased accuracy and consistency in the point and split grinding process, resulting in more accurate hole sizes
• Flutes have a thin nitro carburized surface to provide extra wear resistance along the cutting edge of the point
• Special flute form enhances chip ejection, reduces drill retractions (wood peckering) and improves coolant flow to the tip
• Split point provides the drill with self-centering/non-walking characteristics by giving the drill two starting points
• Split point also reduces the thrust required to penetrate the workpiece
• The superior bronze oxide (gold) ground flute finish reduces friction, allowing outstanding drilling performance with less operator pressure
• JET offers Torque Drive® three ground flats on the shank to provide a strong positive chuck grip virtually eliminating the potential for the drill to slip in the chuck
• The thin web of the JET-KUT® Gold prentice bit permits fast feed rates which make it ideal for drilling work on hardened steels such as 304, 306 and 316 stainless steel
