Hand Tap set of 3 pieces HSS-E DIN 352 - M36 x 4.0

The M36×4.0 three-piece hand tap set by OSD is designed and manufactured according to DIN 352 standards. It has a nominal diameter of 36 millimeters and a thread pitch of 4 millimeters. Made from cobalt-alloyed high-speed steel HSS-E with a surface hardness of 63 to 65 HRC, this tap offers high resistance to wear and heat. The set includes three taps—taper, intermediate, and bottoming—used sequentially to start, deepen, and finish internal threads. The thread angle is 60 degrees, and there are 4 flutes to ensure effective chip evacuation. Each tap measures between 150 to 190 millimeters in length and has a square end for installation in a hand tap wrench.

The recommended pilot drill diameter for this tap is 32 millimeters to ensure precise and secure thread engagement with the workpiece. The suitable manual tapping speed ranges between 4 to 8 revolutions per minute to optimize tool life. OSD’s three-piece tap set provides high machining accuracy and tight tolerance control, producing smooth and uniform threads. This tool is ideal for heavy industries, large mechanical parts manufacturing, and industrial maintenance. Its standard-compliant design and durable materials enhance tool quality and longevity in long-term applications.
