Boring has never been more exciting. Criterion TM modular boring systems have everything you need for your rough and/or finish boring applications. The Cri-Twin® system is designed for either single or double effective cutting so you can rapidly enlarge your bore or reduce the number of passes required. The Cri-Bore® boring system is designed for finish boring applications. For extremely close tolerance boring, the Cri-Bore® micro adjusting boring heads are adjustable in 0.00127mm or (0.00005” (fifty-millionths). The CBER® boring heads are designed for use in live tooling spindles, right angle heads, or any standard ER collet holder.
