Deburring Cutters

Select cutters by matching shank size to your tool, choosing cutter geometry and flute count for the material (single- or double-edge for soft metals and plastics; multi-flute for harder metals), and considering cutter diameter and cutting length to reach the work area without chatter

Common shanks include 1/4" and 3/8" round or hex; choose a shank that fits your drill, rotary tool, or tool holder. Cutter bodies are usually high-speed steel (HSS) or carbide—HSS is tougher for intermittent cuts, carbide holds an edge longer on hard materials; size affects access and finish quality

Budget options typically cost under $50 for basic sets and are fine for occasional light use; carbide or branded specialty cutters cost more but last longer in production environments. Consider buying multi-packs or replacement heads if you need frequent use to lower per-cut cost

Use moderate spindle speeds and light axial feed to avoid overheating; maintain steady contact and avoid heavy side loading. Apply cutting fluid on metals when appropriate, clear chips frequently, and reduce speed as diameter decreases to control surface finish

Keep cutters clean and dry, remove built-up material with a soft brush, protect cutting edges in individual holders or foam racks, and sharpen or replace them when they show dulling or chipping to prevent poor finishes and tool failure

Wear eye protection and appropriate gloves, secure the workpiece, use guards on rotary tools when available, avoid excessive force that can cause breakage, and disconnect power before changing cutters or making adjustments

Look for compatible shank sizes, a range of cutter diameters and geometries for different edges, durable materials like carbide or coated HSS if required by your workload, and clear specifications on RPM limits and recommended materials
