Falcon Toolings manufactures End Mill Holder BT in accordance with JIS B 6339 (MAS-BT) AD. End mill holders are highly suitable and used for mounting straight-shank tools with lateral flat according to DIN 1835 form B (Weldon). All holders are made of forged steel that are highly durable and produce reliable machining output. Specific and low warpage hardened materials are used in the manufacturing of mill holders. Surface hardened HRC 58~60 is the most common base material used in the End Mill Holders which enables great machining performances.
These holders are commonly suitable for the Hardening depth 0.8mm~0.9mm. The taper angle tolerance < AT 3 is achieved in the end mill holder according to DIN 2080. Surface roughness Ra < 0,4 µm and the tensile strength in the core of min. 800 N/mm² after DIN is achieved using these end mill holders. All functional surfaces of the tool piece are fine machined.
