The GARANT solid carbide drill-reamer 12 2795 efficiently combines two operations. Drilling into solid and at the same time finish machining by the 4 reaming cutting edges of the tool creates optimum dimensional accuracy and surface quality in the H7 tolerance zone. Elimination of the usual separate reaming process significantly reduces both direct production times and ancillary production times. In addition the geometry of the cutting edges and guidance chamfers permits precise and economical regrinding. Reaming cutting edges 'Drill cutting edge Drill cutting edge 107
