Hoffmann Group 47 4aBM id eco thread turning toolholder for external threads With internal coolant supply right to the cutting edge. The use of precision nozzles for cooling effectively and efficiently reduces the thermal loading, since the coolant jet is directed optimally between chip and cutting edge. For higher productivity, longer tool life, and higher process reliability. Supplied with: With standard 1.5° shim Note: Coolant transfer available only in conjunction with GARANT eco-system VDI toolholders No. 319001 -319191 or eco retrofit kit No. 317900.

The threads produced are true to DIN/ISO gauge. y j L Partial profile inserts cover a wide range of different pitches, but are not true to DIN/ISO gauge.The external or internal 0 is not cut with the profile. Semi-profile turning inserts cut the complete profile and deburr the tips of the thread flanks. The external or internal 0 is not cut with the profile.
