GBP 57 M 60° HSS-E- PM DIN 13 ISO 2X 6HX h6 DIN Standard 40° 1835 B ≤2.5×D Synchronised blind hole machine tap with internal coolant supply Sturdy version with right-hand helix and shank to DIN 1835-B.Special geometry C for use on machines with synchronised spindle drives. The tap is controlled by the synchronising spindle of the machine. With the latest generation of special DLC 3 coating sp2 for optimum tool life. For use with emulsion (fat content minimum 8%). 13 4275 13 4280 – Form E (lead chamfer: 1.5 - 2 turns) for the deepest possible thread depths. E 13 4285 – With internal coolant supply for maximum tool life. Note: For use on synchronised spindles, the GARANT quick-change 1½ tapping chuck No. 338100 − 338121 with minimum length 13 4280 adjustment (MLA) ensures maximum process reliability.

This operation is thus critical for the quality of the workpiece. Defective threads generally give rise to significant additional costs. Process reliability thus takes absolute priority. However short cycle times and economic production processes must also be considered. Machine tap Special features of a synchronous tap: Long thread part = Due to the short guide part of the synchronous machine tap the guidance range of the tool frictional resistance between tool and workpiece is reduced. This significantly increases the process reliability for thread tapping. Lead chamfer The axial guidance is therefore provided by the machine. Machining (or deformation using a fluteless tap) of the workpiece is performed within this range. This assumes rigid clamping of the tool or the use of our GARANT quick-change tapping chuck No. 33 8100 – 33 8121 with minimum length compensation (MLA) . Caution: Because the tool is rigidly clamped using a Weldon arbor, shrink-fit chuck or collet chuck, the spindle speed must be synchronised with the advance of the axis.
