5 HOW TO USE LONG TYE DRILLS a ing a blind hole y 1. ing a pilot hole y 2. Initial cutting with the long type drill z Use a drill with a larger (fl atter) point angle than the super long type. itsubishi type S is recommended. x Ensure a high precision hole is drilled for the guide. c depth : Approx 1D or deeper. (Adjust the pilot hole depth according to the length of the super long type.) z enetrate the pilot hole at low revolution. ( speed 2 3m/min, feed rate.2.3mm/rev) x Stop the long type drill 1 3mm short of the pilot hole bottom. y 3. the deep hole y 4. retraction z Start cutting at the recommended speed and feed with a non-peck (continuous feed) cycle. z After drilling, lower the cutting revolution about 1 2mm short of the hole end. ( speed of around 2 3m/min) x Retract the drill to the pilot hole depth starting point at a feed rate of 3mm/min. c Finally, clear the hole at a cutting speed of 2 3m/min and feed rate of.2.3mm/rev. a ing and breaking through on irregular faces or angles y 1. Spot facing y 2. ing a pilot hole z achine a fl at on the irregular face by using an end mill or slot drill capable of spot facing. ake the spot face diameter the same size as the required deep hole diameter. z Use a drill with a larger (fl atter) point angle than the super long type. itsubishi type S is recommended. x Ensure a high precision hole is drilled for the guide. c depth : Approx 1D or deeper. (Adjust the pilot hole depth according to the length of the super long type.) y 3. Initial cutting with the long type drill y 4. the deep hole z enetrate the pilot hole at a low revolution. ( speed 2 3m/min, feed rate.2.3mm/rev) x Stop the long type drill 1 3mm short of the pilot hole bottom. z Start cutting at the recommended speed and feed with a non-peck (continuous feed) cycle. y 5. Breaking through y 6. retraction z When breaking through, the cutting edge can be damaged. x A feed rate of.5.1mm/rev is recommended. z Retract the drill to the pilot hole depth starting point at a feed rate of 3mm/min. x Finally clear the hole at a cutting speed of 2 3m/min and feed rate of.2.3mm/rev.
