Thread micro end mill / monobloc

WhizThrill Micro Thread Mill Advantages

B9 grade for extra edge sharpness. Excellent for demanding materials such as Titanium and 316/316L.
15° angle from minor diameter to shank.
Available in many different lengths for each size.
Full profile thread mills from M1,0.
Partial Profile thread mills from M0,5.

Selecting the Correct Micro Thread Mill

1. Partial Profile VS Full Profile

Partial profile thread mills are better for long threads, tougher materials, and unstable machining conditions.
Full profile thread mills are better when tight tolerances of major and minor is required. Cycle time should be reduced, and a completely burr free part is the needed.
2. Grade VS Material

WhizThrill have an uncoated grade 9M, a sub-micron carbide ISO K20-K30. Performs well in soft materials where no coating is needed.
B9 is an AlCrN coating which gives an extra edge sharpness. Tool life will be 4-5 times longer in for example titanium compared with an uncoated tool.
3. Determine Length

Micro thread mills lose a lot of rigidity with increased length. Therefore, always choose the shortest possible tool.
WhizThrill has a 15° exit angle from the minor dimension (D) to shank (d). When possible, make the chamfer before thread milling so that you can calculate the length of the thread from the end of the chamfer.
