Blair Equipment Co., Inc. (Swartz Creek, MI), producers of precision sheet metal holemaking tools and spotweld cutters that are used in automotive body repairs, fabrication and restoration introduces a new line of annular cutters, the Rotabroach® Extended Reach Cutters. The cutters are available in four popular sizes which include 3/8, 7/16, 1/2 and 9/16" diameters. Plus, the new cutters are also available in a convenient kit that contains all four cutter diameters in a molded plastic case for cutting edge protection, plus two pilots and a hex wrench. The kit is designed to keep the cutting tools handy and safe, ready for use — plus safeguards the precision ground cutting edges.
The cutters' design and tooth geometry, based on Blair's time-proven other series of annular cutters, have demonstrated the ability to drill holes faster than twist, spade or indexable drills, plus they eliminate many secondary sizing and finishing operations including deburring. The hardened, precision ground M2 H.S.S. tools also provide longer service life.
The annular Extended Reach Cutters are hollow, meaning most of the hole remains a solid slug. The smaller cutting area at the periphery of the hole, with no center point or dead zone (where SFM drops to near zero) as with typical drills, allows faster feed rates while requiring less thrust. The tools are made in the USA.
