Nakanishi NSK RG-01 Reduction Gear Attachment

A speed-reducing attachment for stone setting, seat cutting, and precision hole drilling, the RG-01 mounts between a compatible micromotor and handpiece and trades rotational speed for torque. NSK gears it at an actual 3.92:1 ratio, nominally 4 to 1.

With the RG-01 in line, output speed drops to approximately one quarter of the speed indicated on the control box while torque multiplies by roughly four, giving the steady, unhurried rotation that delicate stones and controlled cuts require. The attachment adds 1.65 in. to the motor and handpiece assembly, weighs 2.4 oz, and fits all Emax EVOlution and Electer E-Max handpieces and micromotors.

Features

• 4 to 1 reduction gear ratio, actual ratio 3.92:1, for greater torque at low speed
• Reduces output speed to approximately 1/4 of the control box indicated speed
• Multiplies torque approximately 4 times for stronger, steadier cuts at low RPM
• Suited to stone setting, seat cutting, and precision hole drilling
• Mounts directly between the micromotor and handpiece for a streamlined assembly
• Compatible with all Emax EVOlution and Electer E-Max handpieces and micromotors

Compatibility

Fits all Emax EVOlution and Electer E-Max handpieces and micromotors, mounting between the motor and the handpiece.

Notes

• Actual gear reduction ratio is 3.92:1; speed and torque values are approximate.
• This is an optional accessory. Micromotor and handpiece sold separately.
