Data Sheet Date: 18-11-2010 Adjustable Reamers Adjustable reamers are suitable for accurately finishing previously drilled holes to an exact size. The 6 hardened steel blades sit in tapered keyways and expand as they are repositioned along the length of the reamer body. Measuring across the blades along the Parallel Cutting Length (L3) with a micrometer checks adjustment progress of the reamer. Screwed end caps finally clamp the blades in the required finish size position. Blade Hardness: HRC 62-66 Front End Pilot (L2): Short parallel length (L2) aids reamer line up with the drilled hole during cutting with the Tapered Lead Taper Lead: Gradually increases the size of the original hole to the size of the final Parallel Cutting Length (L3) Parallel Cutting Length (L3) Finish cuts hole to required size All dimensions in millimetres Manufacturers Code D02272 D02273 D02274 D02275 D02276 D02277 D02278 D02279 D02280 D02281 D02282 D02283 D02284 D02285 Range Metric Range Inch 6.5-7.0 7.0-7.75 7.75-8.5 8.5-9.25 9.25-10.0 10.0-10.75 10.75-11.75 11.75-12.75 12.75-13.75 13.75-15.25 15.25-17.0 17.0-19.0 19.0-21.0 21.0-23.0 0.256 - 0.276 0.276 – 0.305 0.305 – 0.335 0.335 – 0.364 0.364 – 0.394 0.394 – 0.423 0.423 – 0.463 0.463 – 0.502 0.502 – 0.541 0.541 – 0.600 0.600 – 0.669 0.669 – 0.748 0.748 – 0.827 0.827 – 0.905 L L1 L2 L3 D A/F 85 90 100 105 115 125 130 130 145 150 165 170 180 195 35 35 38 38 38 38 38 38 48 52 55 60 60 65 3 4 5 5 5 5 5 5 5 6 6 6 6 6 18 18 18 24 24 24 25 25 30 34 38 40 40 40 4.0 4.0 4.8 4.8 5.6 5.6 6.3 6.3 7.1 8.0 9.0 10.0 11.2 14.0 3.15 3.15 4.0 4.0 4.5 4.5 5.0 5.0 5.6 6.3 7.1 8.0 9.0 11.2
