Small dust suction plate for dry core diameters 28mm to 92mm. Simple, yet highly effective low cost solution providing 100% dust free efficiency drilling when used in conjunction with our PV25 dust extractor or any other good extraction unit. Because the dust is drawn at source this product is far more effective than the more costly dust swivel accessories that fit to the machine chuck. In addition, because the dust is drawn at source it is acceptable to use either slotted or unslotted dry cores.
