7/8 SINGLE FLUTE 90 DEGREE COUNTERSINK7/8 SINGLE FLUTE 90 DEGREE COUNTERSINK 31048, 2-3/4" OAL 7/8" Diameter, 1/2" Shank Diameter (may vary), 2-3/4" Overall Length, 90-Degree Included Angle. Single fluted countsinks are ideal for chamfering, deburring & countersinking in general purpose applications where finish is not critical. Feed rate's should not exceed .005" per revolution and in applications where increased feed rates and better finish is required we suggest a 6-fluted design. Thus if chattering does occur with this tool, just decrease RPM's and feed rates. We stock 60, 82 and 90 degree angles, but 100, 110 and 120 degree's are available. Solid carbide, TiN coated and steam oxide finish are also available, T&S Salesperson for details!
