35632 Machine Thread Shaper with Lubricating Groove, TiN, DIN 371, HSS-E, M 4 x 0.7

Description

For the non-cutting production of internal threads. Advantages: - Longer service life than taps. - Higher permissible rotation speeds. - Consistent dimensional and profile accuracy. - Higher load capacity of the moulded thread- High resistance to breakage. - No chip removal, no chip problem. Application: - With TiN coating for steel materials up to approx. 900 N/mm². - Unalloyed and low-alloy steels. - Structural steels. - Heat-resistant steels. - Stainless steels. - For long-chipping non-ferrous metals (copper, brass, bronze, aluminium). - Zinc alloys. - For through and blind holes. Lubrication groove: - For optimum lubrication effect at thread depths over 1.5 x D. - Use lubricating, graphite-containing cooling lubricants/oils or add suitable additives
