A­ chatter-free cutter giving an excellent burr-free finish. Capable of deburring and countersinking in one stroke with no ‘back-off’ of tool.
Also free countersinking of aluminium with no secondary bulge. For special applications and exotic materials, a choice of hard coatings is available.

Range includes 1xD, 1.5xD and 2xD lengths (ISO Metric threads). Our quality inserts are now supplied in packs of 10 or 50. Other sizes and lengths are available on request, please ask for further information.

The J100 Series are general purpose HSS straight shank drills with a black oxide finish. Ideal for applications involving steel (including cast steel) cast iron (including malleable cast iron) as well as nickel, brass aluminium alloys and graphite. Their 118° point allows for precise hole alignment and reliable cutting performance whilst the black oxide coating helps reduce heat by retaining coolant on the tool surface. The coating also helps reduce the risk of the tool staining.
