Drill & Reamer Holders - Model DRH

These holders are designed with full floating feature to correct the misalignment that so often occurs between tool and workpiece. The holder floats freely on ball bearing operating between hardened, ground, highly polished rolls which provide automatic radial adjustment to insure alignment of the cutting tool with a previously drilled hold. Chatter, bell-mouthed and egg-shaped holes are eliminated. Adjustment is quick and easy with a simple spanner nut. Boyar-Schultz Model D Floating Reamer Holder is also adaptable for floating drills on special drilling operations. Bushings can be utilized to accept various size tool shanks. The full-floating collet type holder provides Boyar-Schultz reliability with the added feature of replaceable double angle- collets. This new design allows for retrofitting of the older Model D floating holder. The nosepiece assembly will fit current holder, and they can be converted in the customer's plant in less than three minutes.
