Rotary die cutting tool model KC-CX08P2

This kit includes 3,4,5,6,8,10mm hexagon hole broaching cutters.

Before do broaching job, user needs to make base hole first. For 3MM hexagon hole broaching cutter, its factory model is 603. S is distance between 2 edges. On my photo S is D. S is 3.05MM. The base hole diameter D1 needs to be S+0.03 to 0.08MM.  Means D1 to be 3.08 to 3.13MM. So we suggest 3.1MM base hole for making 3MM hexagon hole.

603 S=3.05MM   D1=3.08--3.13MM    We can supply 3.1MM HSS drill bit.

604 S=4.06MM   D1=4.11--4.18MM    We can supply 4.1MM HSS drill bit.

605 S=5.06MM   D1=5.11--5.18MM    We can supply 5.2MM HSS drill bit.

606 S=6.06MM   D1=6.11--6.18MM    We can supply 6.1MM HSS drill bit.

608 S=8.08MM   D1=8.13--8.2MM      We can supply 8.2MM HSS drill bit.

610 S=10.08MM   D1=10.18--10.28MM    We can supply 10.3MM HSS drill bit.

The listing includes above drill bit each size 2 PCS.
