JET 672905 rallonge barre, impérial, 1/2 po, 5 po longueur hors tout

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
