Heule Tool Corp. will feature the DL2 – a small, robust, reliable mechanical deburring tool for 1.00mm to 2.1mm bores in a wide range of materials including steel, stainless steel, titanium, aluminum, and composites at Eastec in booth #5039.
Designed for CNC operation, it ensures high efficiency and process reliability on even and slightly uneven bore edges. With simple but robust construction of just four components, the carbide blade is integrated into the spring to form a single unit.
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, ensuing optimal performance and process safety during high-volume operations. New DL2 tooling is ideal for deburring watch cases, medical and surgical components, and other precision micro machining applications.
Heule DL2 tooling is available for bores from 1mm to 2.1 mm with a maximum deburring capacity of 0.15 to 0.20mm, with common sizes available from stock.
How it Works
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 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 0.5mm 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 0.5mm further than the deburring size. Move out of the workpiece in rapid feed and move to the next hole.

- burr
burr
Stringy portions of material formed on workpiece edges during machining. Often sharp. Can be removed with hand files, abrasive wheels or belts, wire wheels, abrasive-fiber brushes, waterjet equipment or other methods.
- composites
composites
Materials composed of different elements, with one element normally embedded in another, held together by a compatible binder.
- computer numerical control ( CNC)
computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
- coolant
coolant
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
- feed
feed
Rate of change of position of the tool as a whole, relative to the workpiece while cutting.
