Deburring and chamfering tools for sheet metal: 1) Manual chamfering tools - for small quantities, field repairs and jobs without a machine; cheap (tens to hundreds RMB), simple, but slow, inconsistent and labor-intensive; 2) Electric chamfering machines - medium batches, faster than manual, a few thousand RMB, but only chamfer straight edges, not hole mouths; 3) Pneumatic chamfering machines - workshop batch production, efficient, a few thousand to ten-thousand-plus RMB, but need an air supply; 4) Machine countersinks (chamfer drills, spot facers) - used on drill presses, mills and machining centers for hole-mouth chamfering and countersunk holes; efficient, consistent, smooth finish - the most common choice for sheet metal factories; 5) Deburring machines - dedicated deburring equipment (tumbler, brush, electrochemical); for high-volume deburring but expensive. Manual vs machine: 1) Small quantities, odd shapes, field repairs - manual chamfering tools; 2) Hole-mouth chamfers and countersunk holes - machine countersinks/spot facers; 3) Straight-edge chamfering, medium batches - electric or pneumatic chamfering machines; 4) High volume, complex shapes - dedicated deburring machines. The most common sheet metal setup: machine countersinks on a drill press for hole mouths, plus a manual tool for edges - efficiency and flexibility in one.
