The Nitto HSS 12DIA × 25MM model of broaches from Blackwoods
are Australian made, and designed for use with Nitto Kohki Atra Ace magnetic drilling machines and more taper adaptors.
The broaches have a one-touch-cutter, operators simply push the broach into the appropriate area and an incision is made.
No pilot hole is required, and the broaches cut holes three times faster than most conventional twist drills.
The broaches provide a self-centering effect, a feature that effectively extends the life of the cutter.
Suitable for most magnetic based drills, these broaches have a depth of 25mm and diameter of 12mm.
They come individually packed, and style is 25mm depth of cut.
