AIR DRILLING MACHINE (Vacuum Suction Type)

The Gison Vacuum Suction Fixing Base on the GPD-231 can be applied to wet and coarse flat surfaces such as cement wall, lumber plywood, stone back, metal firmly and directly, and free of extra fixing devices.
The Gison GPD-231 Air Drilling Machine can replace the Magnetic Drilling Machine.
The Magnetic Drilling Machine can be only used on iron material.
The Drilling Depth can be showed or pre-set when you are drilling.
With no dust jobs due to wet drilling, high efficiency, smooth holes, precision and longer tool life can be expected

Features:

The conventional suction can only apply to smooth surfaces, but the Gison vacuum suction fixing base can apply to wet and coarse flat surfaces such as cement wall, lumber plywood, stone back, etc.
The vacuum suction holds the machine onto the surface of the wall firmly and directly free of extra fixing devices.( It is necessary to confirm that the vacuum suction holds onto the surface prior to releasing the machine. )
The workpiece and the machine are attached firmly and closely by the vacuum suction, so no moving workpiece will bother the worker.
The air source shared by the vacuum suction and the machine demands one vent pipe only. You don’t need two air sources.
The machine has step-less speed regulation and the max. free speed is 1,500 rpm.
The water yield is valve-controllable and the water comes from either the drill chuck or the bores.
The Drilling Depth Control design can show or pre-set the depth that you are drilling.
The ON/OFF switch controls over rapid and slow feed / escape.
Without the additional vacuum pump (vacuum generator).
The GPD-231 Portable Drilling Machine (Vacuum Suction Type) can replace the Portable Magnetic Drilling Machine and is used on various coarse and flat surface. The Portable Magnetic Drilling Machine can be only used on iron material.

Applications:

The Gison Vacuum Suction Fixing Base of GPD-231 can apply to wet and coarse flat surfaces such as cement wall, lumber plywood, stone back, metal firmly and directly free of extra fixing devices.
The GPD-231 Air Drilling Machine can replace the Magnetic Drilling Machine and be used on various coarse and flat surface. The Magnetic Drilling Machine can be only used on iron material.
