Corner Chamfer End Mills

Corner Chamfer End Mills

Corner chamfer end mills produce angled chamfer cuts on the edges and corners of machined components — chamfering hole entries, breaking sharp edges, cutting lead-ins for thread tapping, and preparing mating faces for welding or assembly. AIMS Industrial stocks corner chamfer end mills in HSS and solid carbide for milling machine and machining centre use.

Chamfer Angle Options

Corner chamfer end mills are available in 30°, 45° and 60° included angle configurations (expressed as the included angle of the chamfer, or as the angle from the axis). 45° is the most common for general edge preparation and hole chamfering in engineering. 30° chamfers are used for deeper, more acute chamfers; 60° for shallower, broader chamfers on plate edges and assembly mating faces. Multi-angle chamfer mills provide several angles in a single tool, reducing tool change frequency.

HSS vs Carbide

HSS corner chamfer mills are the practical choice for low-volume, general workshop chamfering in mild steel and aluminium on conventional milling machines. Solid carbide corner chamfer mills are used on CNC machining centres at higher cutting speeds and where surface finish requirements are more demanding — stainless steel, hardened steel and titanium in particular benefit from the superior edge retention and rigidity of carbide.

Applications

Edge chamfering for assembly fit and appearance, deburring and edge-break on machined components, hole lead-in chamfering before tapping, weld preparation on plate and section steel, and V-groove cutting for inlay and decorative applications.
