Handpiece:
Parts apply precision turning and milling technology and use bearings for high-speed rpm. Achieve high concentricity so the tool can run for a long time without overheating.
Works well with the following handpieces:
| Model # | Photos | Handpiece features |
| HC-110 | .jpg) |
Chuck Style Handpieces: Good concentricity combined with a grooved, non-slip grip design provides a stable and smooth operating experience, ensuring comfort even during extended use. Compatible with tools or drill bits ranging from 5/64" to 5/32" (approximately 2–4 mm) in diameter. |
| HC-120 | |
Reciprocating Power Chisel Handpiece: Ergonomic grip design and unique labor-saving structure. Reciprocating movement is two times as the traditional handpiece, which achieves twice the result with half the effort. For optimum performance, use between 5,000 – 8,000 RPM with forward rotation. |
| HC-130 |  |
Collet Style Handpiece: The tool can fit with 2.35 mm (3/32”), 3 mm, 3.175 mm (1/8”), 6 mm, and 6.35 mm (1/4”) accessories when using different size collets. |
DC24V Brushless Motor：
• Brushless motor control with electronic control compensation. Maintaining high torque from low to high speeds.
• Low noise. Energy efficient. Super long lifespan.
• Brushless motor. No brush. No pollution. No maintenance is needed.
• Low electromagnetic waves. Low electromagnetic wave interference.
• No brush contact with the motor, therefore no sparks while operating.
• Instant run and stop. Stop running immediately after turning off when operating with the on/off foot Switch.
• Power supply will activate overload protection while operating at intense load.
Forward and Reverse Rotation Quick Switch: Do not need to stop rotating before switching.
Here are the advantages of reverse rotation:
• Left-handed users will have better control in the reverse direction.
• Dust and debris fly away in reverse for right-handed users.
• Operating in reverse helps with accomplishing symmetrical grinding and carving techniques.
• When drill bits are stuck, using in reverse is good for “backing out”
• Alternating motor direction makes it easier and faster when polishing metals.
Built-in Variable Speed Controller Dial:
Easy to adjust to a desired speed. This speed controller is a built-in device, therefore is no need to purchase extra. The sturdy and aesthetic design knob offers smooth and responsive variable speed control.
RPM Tachometer:
Make your operation more accurate. Know the exact speed at the moment, without the need to guess the speed.
Flex Shaft:
Spare parts are all precision machined and high concentricity results in longer lifespan. Standard flexible shaft length up to 130cm (51”).
Bench Top Motor Housing with Hanger:
The motor can be placed on a table or hung on a rack securely. The attached hanger is durable and easy to hang.
Exclusive Design Handpiece Holder:
Integrated handle placement feature for convenient single-handed carrying.
On/off foot Switch:
Configured with instant run and rapid stop features.
When some work requires the use of both hands, having a foot Switch will make the work more flexible.
Using electronic signal control, it will stop immediately once turned off which is safer to use and ideal for delicate work.
Hands-free on/off foot Switch and the ergonomic pedal angle provide a comfortable user experience. This not only reduces the risk of injury under prolonged use but also avoids fatigue after using for a long time.
Optional Tool Case：
This tool case not only makes it easy to store and protect tools but also increases work efficiency when tools are easy to access.
Meets the Need for Professional Craftsman:
It has the functions and performance requirements of professionals.
Suitable for Novice and Ideal for Teaching:
The approachable design makes it easy to use and stress-free for beginners. Safe and lightweight. Suitable for schools and studios to teach and use wood/metal/stone carving.
Quality guarantee：
1-year warranty for the motor.
Lifetime repair guarantee.
