HOLZMANN BT1220 Belt and Disc Sander

What the HOLZMANN BT1220 belt and disc sander is for

The HOLZMANN BT1220 is the heavy, steady member of the BT belt-and-disc family, built for shops that sand the same edges all day and want the machine to stay where it was put. The BT1220 works a 1220 x 150 mm sanding belt together with a 228 mm grinding disc, turning at 1400 min-1 on a 230 V motor rated 750 W continuous (S1) and 1125 W intermittent (S6).

Belt run: graphite guide and contact surface

Belt behaviour is the headline feature of the BT1220. A graphite guide on the BT1220 keeps belt speed constant and the belt run smooth, and the graphite-coated contact surface minimises belt friction, which HOLZMANN states prolongs the working life of the belts. On a 1220 x 150 mm belt that friction saving is measured directly in consumable cost.

Stability and table

Stability on the BT1220 comes from mass rather than clamps: 51 kg net and 52 kg gross on a solid stand, so heavy pushes into the 228 mm disc do not walk the machine across the floor. The work table of the BT1220 measures 310 x 190 mm and a mitre fence is fitted for precise angle sanding.

Power supply and duty

The BT1220 connects to a normal 230 V single-phase socket, which matters for small workshops in Georgia that do not have a three-phase feed at the bench. The dual rating of the BT1220 – 750 W S1 and 1125 W S6 – describes a machine that will pull harder for short intermittent loads than its continuous figure alone suggests.

Choosing the BT1220 against its siblings

Buyers usually decide the BT1220 against the BT1220TOP: the BT1220 offers the heavier 51 kg build, the graphite-coated contact surface and the 1125 W S6 rating, while the BT1220TOP offers a larger 254 mm disc and a belt unit tiltable 0-90°. Further down the ladder the BT150-914 and BT203-914 run a shorter 914 x 100 mm belt and the BT75 a 25 x 760 mm belt, so the BT1220 remains the long-belt option for full-length edge sanding.
