Description of 10-15mm and 15-20mm Expanding Countersink Deburring Set
size :2-5 mm 5-10mm 10-15 mm 15-20mm. A brand-new, unused, unopened, undamaged item. This 4 piece Countersink and Deburring Tool Set is ideal for cutting through metal, wood and plastic quickly and easily. Point angle: 90 degree.
These countertop sinks are decent but it's pretty obvious they're just thrown in the bin and taken out when ordered because the raw edges have little dents.
Very comfortable. Non-breaking chamfers that seem to be common on "combination" countersink bit sets. I have to bend the shank of the larger drill bit to fit my drill chucks.
