DB131/DB133 Micro Carbide Drills
A new type of flute design reliably evacuates chips, even with the tinniest drills. This capability ensures that hole depths up to 30 × Dc can be easily achieved with the DB133 Supreme micro drill with its 140° point angle. The DB131 Supreme micro pilot drill features a 150° point angle. Emulsion, oil or minimum quantity lubrication (MQL) can all be used as a coolant with these drills. The DB133 drills without internal coolant are available in a diameter range from 0.020-0.116 in. (0.5-2.95 mm).
