Catalog number: N-SP-M28X2 Features: ●The grooves are twisted, so small curled chips are discharged backwards and chip clogging does not occur, making it ideal for blind hole machining. ●The sharp cutting edge makes it ideal for threading, especially sticky work materials and plastics. ●The tap bites easily. ●Intermittent cutting of pilot holes with keyways is also possible. ●The blade strength is inferior to HT, so the HT shape is more suitable for high hardness materials. Applications: ●For blind hole machining. ●Work material: Low carbon steel, medium carbon steel, high carbon steel. Specifications: ●Nominal size: M28 ●Pitch (mm): 2 ●Shank length: 62mm ●Length of square shank: 20mm ●Number of grooves: 4 Material/Finish: ●High speed tool steel (HSS)
