BIG Kaiser Precision Tooling Inc. has two new indexable cutters: R-Cutter (Pat. P) and BF-Cutter from BIG Daishowa.
The R-Cutter is an ultra high feed front and back radius chamfering mill which features high rake angles that reduce cutting resistance and minimize burr generation. The radius chamfering mill is offered as a single-insert design and a four-insert design for higher feed rates. The coated carbide insert design allows for four indexes, is available with radii of .02-.16 in. (0.508 – 4.1 mm), and is optimized for all steels (including stainless), cast iron and aluminum.
A variety of R-Cutter types are available, including a single insert front chamfering-only design with shank diameters of Ø16 and Ø20 mm, and front-and-back combination chamfering models with cutting shank diameters of Ø10, Ø16 and Ø32 mm. Each model featuring a single insert design allows for cutting in the tightest of spaces.
TheBF-Cutter was exclusively designed for back spot facing of cap bolt holes, sizes M6-M16. It features the world’s smallest square indexable insert (with 4 indexes), and is ideal for all steels (including stainless), cast iron and aluminum. The coolant-through capability helps cool down the back side cutting area, increasing tool life – a feature not available in most other models on the market. The BF-Cutter is available for minimum facing diameters beginning at Ø.433 in. (11 mm) and up to Ø1.024 in. (26 mm). A unique, offset design allows for easy programming – simply offset the centers between the machine spindle and the hole when entering or exiting the hole with the cutter. The minimum hole diameter for possible entry is Ø.256 in. (6.5 mm).
