| Chromated copper arsenate (cca)

| Chuck

| Chuck capacity
|
|
Chuck capacity indicates the largest size full-shank cutting tool (twist drill bits on power drills) a drill's chuck can accommodate. Capacity is a good indicator of the maximum size hole a tool will comfortably bore through a hard metal surface. 1/4 And 3/8 inch drills handle most homeowner needs. Both have higher rpm output and lower torque for fast results. 1/2 Inch drills accept larger bit shanks and have higher torque for tougher jobs and prolonged use in wood, masonry and steel. |
