B040-20 Automated Core Drill – ACD for Asphalt Specimens

( Asphalt )

The Matest Automated Core Drill (ACD) is designed for fast, precise coring of cylinders, prisms, and slabs prepared with Matest compaction machines. It produces cores of 12 mm to 150 mm diameter from ASC prisms, ARC slabs, gyratory compactor, or SGC specimens (using optional cylindrical jig).

The ACD handles specimens up to 400 mm tall with a three-position sliding fixture for accurate positioning. Its adjustable clamping mechanism ensures stable specimen support during drilling. Multiple core supports allow two or three cores from a single prism without measurements. The high-performance motor offers three selectable speeds for consistent, reliable coring. Protective covers provide safe visibility and comply with CE Safety Directive.
