HHIP 2007-0051 High-Speed Steel 3 Flute Straight Shank Solid Pilot Counterbore, M3 x 3.4mm

.HHIP 3 Flute straight shank solid pilot counter bore is made of high speed steel. Cap screw is M3. Cutter diameter is 6.0mm. Shank diameter is 5.0mm. Overall length is 71mm. Pilot diameter is 3.4mm. Continuous pilot counter bores cut rapidly, smoothly and accurately, producing long spiraling chips rather than small metal particles. The pilot extends the full length of the flute portion of the tool. As cutter flutes are ground back due to wear, a new section of pilot becomes exposed. The pilot head may be cut off to any desired length when repeated sharpening makes it too long for practical use. Continuous pilot counter bores have a life many times that of the conventional type counter bore.
