Gauge Length | Orientation: Radial","description":"\u003cp\u003eUsed in CNC machining centers where multi-face or compound-angle operations are required without repositioning the workpiece, the BIG Daishowa BCV50-AGU\/NBS20-315 is a BIG-PLUS CAT50 universal angle head with an NBS20 New Baby Chuck output spindle. The output spindle angle is fully adjustable from 0 to 90 degrees in 1 degree increments, and the cutter head rotates a full 360 degrees, enabling a wide range of machining orientations from a single tool station. Speed ratio is 1:1 with a maximum reverse rotation speed of 4,000 RPM as confirmed on the nameplate. The gauge length is 315 mm (approximately 12.4 inches). The BIG-PLUS CAT50 dual-contact shank engages both the taper and the spindle face simultaneously, providing superior rigidity compared to standard CAT50. The NBS20 collet system accepts a range of tool shank diameters and is compatible with BIG Daishowa New Baby Chuck collets. The angle indexing mechanism uses a precision detent pin system with positions marked 0 through 9 on the face plate, visible in the photos. A caution label on the body instructs not to overtighten the angle adjustment pin. BIG Daishowa is recognized as a premium manufacturer of precision tooling systems, and the AGU universal angle head series is among their highest-capability angle head offerings, suitable for drilling, tapping, milling, and keyslotting in restricted or compound-angle locations.\u003c\/p\u003e\n\n\u003cp\u003eStock # 0426-02119\u003c\/p\u003e","brand":"BIG Daishowa","offers":[{"title":"Default Title","offer_id":49624874615024,"sku":"m02119","price":7999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0797\/6648\/7280\/files\/A0F0F57E-4CBD-4ED0-97F9-DB03FFD04F5D.jpg?v=1777409889","url":"https:\/\/mroexchange.com\/products\/big-daishowa-universal-angle-head-bcv50-agunbs20-315-cat50-nbs20-collet-output-124-in-gauge-length-orientation-radial-02119","provider":"MRO Exchange","version":"1.0","type":"link"}
