Spot Face/Counter Bore Tools

Shenoy Engineering offers large Spot Face/Counter Bore Tools. Producing large diameter of front spot facing or counter bore is time-consuming and cumbersome operation. Suitable tools for such operations are generally not available. Even the largest utility inserts available in standard range can cover spot facing only up to certain diameters. Using the single point tool or using interpolation method in CNC machines are time consuming and uneconomical. The company offers an effective solution for making large diameter of spot face/counter bore tools, using the generally available, indexable, standard carbide inserts. Multiple, staggered cutting edges, displaced circumferentially in a specially designed counter bore tool can produce any large diameter of spot facing or counter bore. Parallelism and step-free machined surface are ensured by parallel cutting edges, which has become possible by a highly skill oriented pocket milling operation. Apart from the advantages of heavy material removal from the inserted carbide, the in-built chip breakers in the inserts facilitate faster chip evacuation. Use of forced coolant is recommended for chip evacuation from the deep counter bores, so as to retain the good finish on the counter bored surface. Chips can smoothly flow out through the well designed, generous gashes on the tool shank. Multiple cutting edges of the counter bore/spot facing tool, together with guiding pilot, act as the balancing factors while performing heavy material removal, especially in deep counter bores. This factor, in turn, will ensure good surface finish and accuracy, repeatedly. Pilots are detachable type, which permit the use of different dia of pilots for the same dia of counter bore. This feature also enables an easy replacement of damaged /worn-out pilots. However, smaller counter bore tools are offered with integral pilots. The body of the tool and the pilot are generally made of case hardened steel, case hardened and ground. The front spot facing tools are offered with any type of holding shank – straight (cylindrical), so as to suit your existing side lock holders or Morse Taper, so as to suit the spindles of your drilling machine. Any other tapers can also be provided.
