03 Key Features

Built for the job site.

// 01

Spark-free for hazardous-zone work

Standard plate-edge chamfering tool on oil & gas, shipyard and refinery sites where electric tooling is restricted by ATEX / Class 1 Division 2 requirements.

// 02

DJ / SDJ — fast C / R chamfers on long edges

Cutter-wheel head delivers 2 – 3 m/min on straight plate edge. The workhorse for shipyard hull plate, bridge frame and structural-steel chamfering at speed.

// 03

QD-R3 — carbide inserts + R16 inner-bore reach

Indexable carbide tooling lasts longer than grinding wheels (8 cutting edges per insert). R16 minimum inside radius allows bolt-hole and small-cutout chamfering that wheel-head tools cannot reach.

// 04

Handheld — operator carries to the work

3 – 4 kg single-operator tools. The right answer for curved edges, holes, corners and any geometry that defeats fixed and traveling machines.

04 Industry Applications

Where this series earns its keep.

Shipyard hull plate chamfering

Plate edge R / C chamfering on hull, bulkhead and deck plate. DJ / SDJ standard for long-edge work; QD-R3 for cutouts and bolt holes.

See shipyard hull plate chamfering solutions

Bridge & structural-steel R / C chamfers

Safety chamfers on structural beam, frame and plate edges per AWS D1.1 and bridge-construction specs. Bolt-hole chamfering for fatigue-life requirements.

See bridge & structural-steel r / c chamfers solutions

Refinery & offshore plate prep

Plate edge prep on refinery and offshore platform structural work where spark-free operation is the access requirement.

See refinery & offshore plate prep solutions

06 FAQ

Common questions about the DJ / SDJ / QD-R3 Series.

Can't find your answer?

DJ/SDJ or QD-R3 — which should I order?

DJ / SDJ for fast C / R chamfering on long straight plate edges (cutter-wheel head, 2 – 3 m/min). QD-R3 when you need (a) inner-bore access (R16 minimum radius — bolt holes, cutouts), (b) longer tool life (carbide inserts vs grinding wheel), or (c) precise R-radius geometry. Many shipyards stock both for the complementary geometry.

Why pneumatic instead of HDL handheld edge miller?

HDL is a precision edge miller — produces a true V / Y bevel for weld prep, with operator-skill-dependent uniformity. These pneumatic tools are faster (2 – 3 m/min) and simpler (R / C chamfer only, not full bevel prep). Use HDL when the chamfer feeds into a weld; use DJ / SDJ / QD-R3 when the chamfer is for safety, paint adhesion or cosmetic edge break.
