These three Boring Bars (Ø1/2" x 10", Ø3/4" x 13" and Ø1" x 13") will meet the needs of most small engineering workshops.
Each bar has a dedicated micrometer, which can be accurately positioned over the end of the cutting tool to allow precise measurement and advancement by 0.001" increments.
The carrier arrangement is particularly well concieved. A soft centre is produced from bar to be held in the 3-jaw chuck and trued up at 60° in situ before boring. Each bar is fitted with its own captive carrier, armed with a Ø1/2" pin which sits securely between the chuck jaws to drive the boring bar. No more floppy carriers "tied" to catch plates!
Supplied as a kit of easily machined parts including steel bar, gunmetal micrometer castings, steel for the carriers, HSS cutting tools, drawing and instructions.
