03 Key Features

Built for the job site.

// 01

Specialized gear geometry

Designed specifically for the burr and defect removal that gear, ring and sprocket finishing requires. Wheel profile and balance differ from general-purpose grinders.

// 02

15,000 – 16,000 r/min spindle

High-speed operation matches the small contact patch of gear-tooth chamfering — produces a uniform finish on the chamfer flat without burning the tooth flank.

// 03

S60-470 extended reach

Long-shaft variant for inside-bore work on ring gears, internal splines and bearing-race finishing — reaches geometry inaccessible to standard grinders.

// 04

≤ 85 dB(A) noise

Quieter than typical pneumatic die grinders. Meets workshop noise limits in automotive and machinery production cells where multi-station grinding generates additive noise exposure.

// 05

Integrates into mechanized cells

Spark-free pneumatic drive is compatible with automated gear-finishing cells where electric tooling introduces ignition risk in oil-mist atmospheres.

06 FAQ

Common questions about the S35A · S35 · S60 Gear Series.

Can't find your answer?

Why a specialized gear grinder vs general die grinder?

Wheel profile, balance, and spindle stiffness are tuned for the light-contact tooth-flank chamfering work that defines gear finishing. General die grinders work for one-off gear repair, but production gear cells where tooth-by-tooth chamfering must be consistent need the specialized head.
