2 Comparison of products Performance comparison P 2/ 13 Test conditions Extension power supply cord: Cross-sectional area/1.25mm2, length/60m Test (1) Cut a 1,000mm long groove in Taun at a depth of 6mm using 6mm straight bit. Test (2) Cut a 1,000mm long groove in White Meranti (Me la pi)*1 at a depth of 6mm using 1/2" (12.7mm) straight bit. Test (3) Cut a 1,000mm long groove in Taun at a depth of 6mm using 6mm straight bit. Test (4) Cut a 1,000mm long groove in Taun at a depth of 6mm using 12.7mmstraight bit. Note: 1) The test results depend to a great extent on the hardness of materials, etc. 2) The numbers in the bar charts below are relative values when the capacities of BOSCH PR20EVSNK and Makita RP0900 are indexed at 100. *1: In Test (2), we used White Meranti (Melapi) that requires low cutting torque instead of Taun that requires high cutting torque. This is because BOSCH PR20EVSNK cannot smoothly cut Taun, which can be cut with ease by Makita RT0700C.
