Frequently asked questions
How do I decode a toolholder code like MWLNR2020K08?
M = holder style (negative insert, lever clamp), W = insert shape (WNMG trigon), L = lead angle (95°), N = negative clearance, R = right-hand (cutting toward chuck), 20 = shank height (20 mm), 20 = shank width (20 mm), K = overall length code, 08 = insert size. Read the ISO 5608 standard for the full table.
Right-hand vs left-hand toolholder — which do I need?
Right-hand holders cut with the spindle rotating counter-clockwise viewed from the tailstock (standard CCW spindle on most lathes). Left-hand is used for back-turning, main-spindle CW rotation, or specific part geometries. If your machine runs standard CCW and cuts toward the chuck, buy right-hand.
Which toolholder matches a DNMG insert?
DNMG (55° diamond, negative) pairs with holder styles D__NR/L — most common are DDJNR (93° lead, profiling) and DDHNR (107.5° lead). Lead angle affects cutting force direction and accessible geometry.
Shank size — 20 mm vs 25 mm?
Match the shank to your lathe tool post square opening. 16 mm for small bench lathes, 20 mm for most Indian 200-300 mm swing lathes, 25 mm for 400+ mm swing and heavier CNC turning centres. Running a smaller shank on a deep cut causes chatter; larger shank needs a bigger tool post.
Do your toolholders include a spare clamp screw?
Yes — every holder ships with the correct clamp screw and torque setting listed. Use the Torx/hex key that matches the screw, and tighten to the torque printed on the holder body to avoid stripping the seat.
