FAMAG 1775.505 Machine Countersink Set contains five seven-edged countersinks in one wooden case, each with a 90° point angle built to solve the chatter problem that plagues softwood countersinking. The irregular pitch on every cutter breaks up vibration as it bites, giving a clean, even countersink rather than a chattering, torn one.
Covers 10mm, 13mm, 16mm, 20mm and 25mm, so you've got the right diameter to hand for most jobs without hunting through separate purchases.
Good to reach for when:
- Countersinking screw heads across a range of sizes in softwood, where standard countersinks tend to chatter and leave a rough edge
- Working with a hand drill rather than a pillar drill, since the irregular pitch keeps cutting smooth even without a fixed setup
- Finishing veneered or laminated panels, where a clean edge matters and tear-out isn't an option
- Countersinking in hardwood or general timber, with a size to suit most fixings
Fully CNC ground from alloyed tool steel with parallel shanks, so each one runs true and holds its edge over repeated use. The wooden case keeps all five organised and protected between jobs.
