Different Bearings can be used in conjunction with this range of Mini Groovers to give various cut depths when using the TTLDTA type of arbor.
The TTLDTA arbors are for use with bearings and come fitted with a TT5/8B16. The TTLDTA-1/4NB does not have a bearing fitted. The MGA6.35 arbor is for use without a bearing .
Z=Number of flutes. RPM=Maximum revolutions per minute
Groove Depth with various bearings are as follows
For 36mm diameter groovers TTB14 = 11mm, TTB15 = 10.5mm, TT5/8-B16 = 10mm, TTB17 = 9.5mm, TTB18 = 9mm, TTB19 = 8.5mm, TTB20 = 8mm, TTB21 = 7.5mm, TTB22 =7mm, TTB23 =6.5mm, TTB24 =6mm, TTB25 = 5.5mm
For 40mm diameter groovers TTB14 = 13mm, TTB15 =12.5mm, TT5/8-B16 = 12mm, TTB17 = 11.5mm, TTB18 = 11mm, TTB19 = 10.5mm, TTB20 = 10mm, TTB21 = 9.5mm, TTB22 =9mm, TTB23 =8.5mm, TTB24 =8mm, TTB25 = 7.5mm
For 50mm diameter groovers TTB14 = 18mm, TTB15 =17.5mm, TT5/8-B16 = 17mm, TTB17 = 16.5mm, TTB18 = 16mm, TTB19 = 15.5mm, TTB20 = 15mm, TTB21 = 14.5mm, TTB22 =14mm, TTB23 =13.5mm, TTB24 =13mm, TTB25 = 12.5mm
