Heule Precision Tools’ DL2 deburring tool is a compact mechanical deburring tool for 1.00-2.1-mm bores in a wide range of materials, including steel, stainless steel, titanium, aluminum, composites and more. Designed for CNC operations, it is said to provide high efficiency and process reliability on even and slightly uneven bore edges. With simple, robust construction of just four components, the carbide blade is integrated into the spring to form a single unit. According to the company, this ensures proper spring tension for the guiding and cutting forces of the blade and makes it easy to change blades without tweezers or a magnifying glass.
The DL2 uses smart tool concept with internal blade cooling. Coolant is supplied through the tool and guided directly to the cutting edge of the carbide blade, providing optimal performance and process safety during high-volume operations. DL2 tooling is said to be well suited for deburring watch cases, medical and surgical components, and other precision micromachining applications.
Heule DL2 tooling is available for bores ranging from 1-2.1 mm with a maximum deburring capacity of 0.15-0.20 mm, with common sizes available from stock.
The DL2 tool must be used in counterclockwise rotation and can be used for front and back deburring or back only deburring. Throughout the entire machining process, neither a change in the direction of rotation nor a stopping of the spindle is necessary. The tool’s cutting edge is positioned in rapid feed above the front of the hole to be deburred.
At working feed, the edge is deburred on the front edge of the hole until the blade has fully retracted. In rapid/increased feed, the tool passes through the workpiece without damaging the surface.
Position the blade 0.5 mm deeper than the existing burr to safely reach the new starting position. In working feed, the hole on the underside of the workpiece is deburred. The blade should travel 0.5 mm further than the deburring size. Move out of the workpiece in rapid feed and move to the next hole.
