Hole saw holesaw hm

A fantastic hole saw with a hard metal blade for quick perforation in most materials. Cuts more than 5 times faster than traditional bimetal hole saws, and has an unbeatable service life. Cuts in: wood, particleboard, MDF panels, laminate, plastic, plaster, light concrete, Leca, and glass fibre, as well as tiles and stone materials up to a hardness of 6. Not for use in steel or metal materials. The hole saws have standard threading and follower bores. PLEASE NOTE! Does NOT fit standard hole saw holders with SHORT centre bore, because the HM hole saw is deeper than standard bimetal. Use special holders with a long centre bore, or replace the short centre bore in the standard holder with a longer one.
