Model RMAW-2F TWO-FACE HOLDING BLOCK FOR SMALL WORKPIECE［Application］
Suitable for holding workpieces in various operations such as grinding and light
duty cutting, measurement and assembly work.
［Features］●The strongest holding power among small permanent magnetic types.
Furthermore, by making the pole pitch ﬁner, this model holds small and thinworkpieces firmly. This model is also effective for holding relatively large
workpieces that cover the whole attractive face.
●The top and bottom faces can be turned on and oﬀ individually. It can be set
easily on the machine table or work table to shorten the setup time.
●Since a workpiece can be held on its side face, workpieces can be held
vertically or on three faces. ※When a workpiece is held on the top face orbottom face and the side face simultaneously, the holding power of each facedrops.
●By using tapped holes on three side faces and bottom face, stoppers andﬁxtures can be mounted.

HOLDINGTOOLS［Application］
These blocks can hold workpieces during electric
discharge machining and grinding. They can also be
used as holding tools for assembly and light duty
machining.
［Features］●The both sides can hold workpieces and can beturned on and oﬀ individually. (2F type)●They are secured to the work table by turning on andoﬀ the magnet. (2F type)●The side faces (ON/OFF switchover face) can also
hold workpieces. (2F type)●They are secured to the work table using tappedholes provided on the mounting face. They can also
be secured by having them held by a magnetic
chuck. (1F type)●The operation part is provided on both side faces tofacilitate on/oﬀ operation.
●Light weight for easy positional adjustment.
●The operating handle is detachable and does nothinder the work.
●One set of two blocks has been machined andﬁnished together.
●They are of drip-proof and oil-resistant construction
to allow them to be used in ﬂuid.

Freely workable permanent magnetic block

MM2F-512
MM3F-612［Application］
These blocks are designed to allow deep engraving such as
grooves and steps on the attractive face to ﬁt workpiece shapes
when holding workpieces.
［Features］●The attractive face can be removed up to 10 mm deep from thesurface of the new block.
●As workpieces can be fitted in grooves, a large machiningpressure can be used. Also cemented carbide workpieces,which are diﬃcult to hold by a magnetic chuck, can be secured
by using these blocks to enable grinding.
●These blocks can be mounted on the magnetic chuck work face.
●There are two types; a magnetic force ON-OFF type and a typenot equipped with an ON-OFF function.

KT-1［Application］
These blocks are used in combination with amagnetic chuck as an auxiliary tool to hold roundbars and sheet-like workpieces that are diﬃcult tohold on the work face alone.
［Features］●Since these blocks are not magnetizedthemselves, they are placed on a magnetic chuck

to induce magnetism to hold workpieces.
Magnetism can be induced on two faces of the〈KT-2、3、4〉
