Tungsten Carbide Rotary Burr 6mm Shank Tree Shape
Tungsten carbide rotary burr 6mm shank tree shape
6 mm-shank tree carbide burr that stays sharp after 30 aluminium ports. See why EU mould shops swap their old HSS burrs for this exact shape—and which insert grades we bin-sort to keep every flute balanced.

Why this shape matters
The tree radius lets you reach into acute corners, deepen ports and engrave undercuts without changing tools. Double-cut spiral gives small chips and low pull, so 5-axis robots run it unattended.

Recommended companion inserts & holders
We cut the flutes on the same Walter Helitronic machines we use for our milling inserts-so run these inserts when you need a follow-up finish:
CCGT09T302-ALU (polished, 0.2 mm corner) for Al after burr roughing
VCGT160404-FS for 30° chamfer on steel edges deburred with the burr
APMT1135PDER-MM for high-feed clean-up on deeper tree-shaped pockets
Holder: SCLCR/L 1212F09 for CCGT, MVJNL 1616H16 for VCGT, end-mill holder Ø20 mm for APMT-same shank stock as the burr collet, one change-over.
