BIG Kaiser Precision Tooling Inc.’s R-Cutter and BF-Cutter from BIG Daishowan features high rake angles that are designed to 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 0.02”- 0.16” 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 16 and 20 mm, and front-and-back combination chamfering models with cutting shank diameters of 10, 16 and 32 mm. Each model featuring a single insert design allows for cutting in the tightest of spaces.
The BF-Cutter was designed for back spot facing of cap bolt holes, sizes M6-M16. It features a small square indexable insert (with 4 indexes) and is ideal for all steels (including stainless), cast iron and aluminum, the company says. The coolant-through capability helps cool down the back side cutting area, increasing tool life. The BF-Cutter is available for minimum facing diameters beginning at 0.433” and up to 1.024”. An 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 0.256”.
