1. PRODUCT NAME
Hitachi Disc Grinder, Models PDA-100M [100 mm (4")]
2. MARKETING OBJECTIVE
The current Model PDA-100D has obtained high evaluation for its highly durable aluminum housing in the Asian
market. However, there is an increasing demand for a durable disc grinder having double-insulated construction
with a high insulation class resin housing. To cope with this demand, we developed the new Model PDA-100M
based on the current Model PDA-100D. The motor of the new Model PDA-100M is more durable than that of the
current Model PDA-100D thanks to the double insulation construction. We aim to expand our market share with
the new Model PDA-100M.
The main improvements are as follows:
The motor is so designed that commutation sparks are minimized during operation in order to increase the
service life of the brush, commutator and the motor.
The wear resistance of the coil is increased by attaching the protect tape to the coil end at the fan side of the
armature.
The iron bearing bushing is adopted as the bearing of the resin housing in order to increase durability of the
housing.
Use of thick copper wires increases the motor input and the overload durability owing to reduction of loss.
3. APPLICATIONS
Removal of casting fin and finishing of various types of steel, bronze, aluminum, and other metallic materials
and castings
Grinding of welded sections, or sections cut by acetylene torch
Grinding of slate, brick, marble and similar materials
