Small Diameter Rough Boring Tools

BIG Kaiser Precision Tooling Inc. has introduced a small diameter indexable rough boring solution for a range not previously available. The new MW boring head permits small-hole rough boring in a range of Ø16 mm-21 mm (Ø630"-.827") and is ideal for semi-finish boring operations of workpieces with die cast holes.

Unlike other boring tools from BIG Kaiser, the new MW does not feature the modular KAISER KA/KAB connection. Built with a Ø20 mm straight shank, the product performs best when paired with a milling chuck at fixed bore depths up to 4xd.

Efficient chip evacuation was a major consideration in the design of this tool. A spiral groove carved into the body facilitates clean and quick chip removal with the help of coolant holes near the end of the groove. However, for blind-hole situations, an additional center-through coolant option was added to aid in chip evacuation. "Simple stop screws make choosing coolant preferences fast and easy," said a company spokesperson.

The two opposing die-steel insert holders feature a precision serrated mounting system, providing a secure and rigid connection similar to the KAISER 319 SW series. The insert holders are marked with a scale for coarse setting, and the radial adjustment screw allows for fine-tuning due to its .008" pitch. Coated inserts are available for common materials like steels (including stainless), ferrous materials such as ductile and cast iron, as well as non-ferrous materials like aluminum.
