DUAL-CONTACT TOOL HOLDERS OVERVIEW
BIG-PLUS TOOLING SYSTEM
BIG CAPTO TOOLING SYSTEM, ISO 26623-1
HSK TOOLING SYSTEM Dual-contact system featuring a 1:10 taper in accordance to ISO & DIN standards. Since HSK is a hollow taper shank, the material plays a critical role for optimum performance. We use carefully selected high-grade alloy steels, and all critical features are finished after heat treatment.
Polygon tapered dual-contact system (1:20 taper) where the face and taper of a machine spindle and tool holder are in contact. This modular tooling system strengthens the performance of milling and turning operations for MTCs. The trademark Capto is licensed from Sandvik Coromant.
Simultaneous Taper & Flange Fit BIG-PLUS surpasses all other spindle concepts while offering interchangeability with existing machines and tool holders. • Improved surface finish & dimensional accuracy • Extended tool life • Prevention of fretting corrosion caused by heavy cutting • Elimination of Z-axial movement at high speeds
FIT
The BIG-PLUS spindle system is based on the most current available standards in ASME B5.50, JIS B6339 and DIN 69871.
Variety A wide variety of rotary tool holders such as the high-precision MEGA CHUCK series are available, as well as a modular turning tool system for MTCs. Excellent Repeatability The perfect fit of the polygon taper to drive spindle rotation ensures high repeatability. Excellent Runout Accuracy The combination of a self-centering 1:20 taper and the long taper edge ensures stable runout accuracy.

Face-To-Face Clamping
Clamp Bolts
Secure and Rigid Clamping Type S Cartridges are located in the basic holder by means of a precision ground pilot and secured by two opposing radial screws with a 15º taper. With a slight offset to locating sockets, high face-to-face clamping force of the two components is generated. To maintain precise locations and orientation, an additional locating pin is included for positive transfer of cutting torque.
Simple and Positive Clamping Type F uses two clamping bolts that press the cartridge onto the basic holder. The torque is transmitted by an interlocking drive slot.

Safe and Easy Clamping of Inserts The double-clamping system simultaneously pushes an insert downward and draws it into the contact faces to achieve secure and rigid clamping.

Ultra-high feed chamfer mill for front and back radius chamfering of .02"-.16". Single-insert models or four-insert models for higher feed rates.
C-Cutter Mini Universal Type Adjustment from 5º to 85º with a hex key.
High-performance chamfer cutter increases the feed rate up to 400% by using four inserts and reducing the cutting diameter to the lowest limit. We offer various models that can do front chamfering at 30º/45º/60º angles, front/back chamfering at 45º angles, and even chamfering for bolt/ tap holes that fit M8-M20 taps.
Four Indexes Unique insert geometry with excellent sharpness. High rake angle reduces cutting resistance and minimizes the generation of burrs.
