Specification Chart / Drilling and Tapping dual-purpose type
Notes:
- Select a model based on workpiece specifications, machinability, tool specifications and cutting speed.The maximum drilling capacity shown above is the value at a drilling depth of twice the drill diameter.Tapping capacities are conditional on the depth of tapping being limited to 1.5 times of the tap diameter.
- If the maximum drilling capacity exceeds the chucking capacity, special tools (with steps) shall be prepared by the customer.
- If your drilling and tapping needs exceed the figures in the capacity chart, please contact the nearest sales office.
- ER collet is adopted for spindle nose. Use collet ER-GB when chucking a tap.
- Misalignment between a pre-hole and a tap can cause early tap damage, select a tap holder.
- A servo motor for feed is with a holding brake, “B” is added to the end of SELFEEDER DUO model number.
- AL : Aluminum(ADC12) , FC : Cast iron(FC200) , ST : Steel(S45C)
Specification Chart / Dedicated to Tapping
Notes:
- Select model and spindle speed based on workpiece material, machinability, tap diameter and material, cutting speed, and other factors.
- Tapping capacities are conditional on the depth of tapping being limited to 1.5 times of the tap diameter.
- If your drilling and tapping needs exceed the figures in the capacity chart, please contact the nearest sales office.
- For details on spindle style and tap mounting, please refer to the single-spindle tapper head specifications.
- A servo motor for feed is with a holding brake, “B” is added to the end of SELFEEDER DUO model number.

10,000min-1 Drilling and Tapping Specifications
As semiconductor-related parts and electronic device parts become smaller and more precise, the need for precision drilling and tapping is increasing.Our specifications of Max. 10,000 min-1 are ideal for machining small, high-precision mass-produced parts.
Features
Feature for drilling
High-speed spindle rotation enables small-diameter deep hole drilling and high-precision drilling with carbide drills, etc.
Easy to modify machining capacity by changing motor spindles.
Feature for Tapping
100 holes can be tapped per minute
Improved production efficiency for small, high-precision mass-produced parts.
Minute expansion/contraction floating mechanism built into the main spindle.
Absorption of slight errors when switching between tap rotation and feed improves tapping accuracy.
- Error absorption reduces cutting resistance on tapping tools and improves their lives.
