6mm 8mm 10mm for solid drill bits hole saw cutter, 12mm-60mm for Hollow hole saw cutter Features: Time saving:The annular cutters have fewer teeth and less wear, therefore with an annular cutter holes can be made at higher or faster cutting speed and a faster feed rate of the drilling machine. Energy savings:Because annular cutters do not have to drill/cut through the complete work piece, they require less thrust and thus less energy to drill through material. More finishing:The hole made using an annular cutter is more finished, precise and accurate. Easy Using:Due to the unique geometry of the annular cutters, making holes at awkward angles is also very easy. Re-sharpening:can be easily re-sharpened on a grinding machine and can be re-used for drilling. Re-grinding can be done until the desired cutting length is available on the annular cutter High-speed steel M2 material to meet most requirements. |
