Frequently Asked Questions

Q: What materials are these chamfering end mill bits compatible with?

A: These 90-degree 3-flute HSS chamfering bits are compatible with a wide range of materials up to 65 HRC hardness, including stainless steel, carbon steel, aluminum plate, thin iron plate, PVC sheet, insulating board, and wood. They are ideal for metalworking and woodworking applications alike.

Q: Can I resharpen the blades, and how do I maintain these bits?

A: Yes! The blades on these titanium-coated chamfering end mills are designed to be re-ground without needing to remove the tool from the holder. This convenient maintenance feature helps extend tool life and keeps you working without unnecessary downtime.

Q: What sizes are included in this 6-piece chamfering drill bit set?

A: The set includes six bits in the following diameters: 6.3 mm, 8.3 mm, 10.4 mm, 12.4 mm, 16.5 mm, and 20.5 mm — each 61 mm in total length. This size range covers most standard countersinking and deburring tasks in both professional and home workshop settings.

Q: What is the advantage of the 3-flute design over a single-flute chamfering tool?

A: The 3-flute design efficiently evacuates chips generated during chamfering, reducing the risk of tool blockage and heat buildup. This results in a smoother finish, faster operation, and a longer-lasting cutting edge compared to single-flute alternatives.
