Medium-sized steel frame single-flute drill grinder EPDG-320
One-letter drill grinding machine for diameters from 3mm to 20mm. Anyone can easily grind to a one-letter shape with a second relief. Can also grind carbide drills by replacing with SDC wheels.
The Fast Tech Drill Sharpener can grind drills from 3mm to 20mm into an optimal flat shape for thin plate drilling, regardless of whether the operator is a beginner or a veteran. Furthermore, by grinding the second relief angle, it can also grind to a split point (X-shining), making it a revolutionary drill sharpener. By holding the drill in a collet holder and positioning it, you simply insert it into the grinding unit to grind the flat shape, the second relief angle, and the split point (X-shining). The holder, which incorporates unique patented technology with built-in bearings, prevents collet wear, eliminating concerns about drill misalignment. You can also adjust the chisel width by adjusting the second grinding unit. Broken drills that are not used in the factory and drills that have lost their cutting edge can be easily restored, contributing to cost reduction and efficiency within the company. A CBN wheel for high-speed steel drills is included as standard, but if you use the optional SDC wheel, it is also possible to grind carbide drills. Note: Drills that are broken and have no groove left, or drills that are too short to be held by the collet, cannot be ground. [For more details, please refer to the catalog.]
basic information
**Main Features** An easy-to-use drill sharpening machine for steel frames that anyone can operate. ■□■Features■□■ ■ Can sharpen drills from 3.0mm to 20.0mm with a single machine. ■ The thinning is uniform, and the secondary relief angle can also be sharpened. ■ To sharpen the secondary relief angle, the drill tip becomes X-thinned, allowing for excellent bite and drilling without a pilot hole. ■ The size of the tip's peak can be adjusted. ■ The tip angle can be changed from 165° to 180°. ■ Tapered drills and nose drills can also be sharpened. ■ End mill shank drills can also be sharpened. ■ Drills are securely held with an ER collet. ■ The built-in bearing holder prevents collet wear and avoids misalignment due to collet wear. ■ The sharpening unit also has built-in bearings, resulting in very good operability. ■ A high-performance motor allows for continuous operation for one hour. ■ Comes standard with a detachable power cable. ■ Can be used with a single-phase AC 100V power supply. ■ Size: L185 x W385 x H175mm ■ Weight: 21kg

Applications/Examples of results
■It is ideal for re-sharpening drills used for drilling holes in thin plates such as steel plates, steel frames, and H-shaped steel. ■When using a regular drill to make through holes in thin plates, burrs can occur on the back side, but by using a drill sharpened to a chisel shape, the occurrence of burrs can be suppressed. ■The optimal thickness of steel plates for holes suitable for chisel sharpening is up to 1/2 of the diameter of the hole being drilled. For example, if the plate thickness is 10 mm, a drill sharpened to a chisel shape is suitable for drilling holes with a diameter of 5.0 mm or less.

Steel frame drill sharpening machine thinning shape This is the tip shape of the drill sharpened by the steel frame drill sharpening machine EPDG-320. Not only is the candle blade (straight sharpening) well-defined, but the second relief angle is also properly sharpened, resulting in a split point (X thinning) at the tip. Due to its excellent bite, no pilot hole is necessary.

Prevents wear of the collet with built-in bearings. When tightening the collet, a very strong force is applied to the collet holder, which can cause wear over long-term use. If this part wears down, it can lead to misalignment in the collet, potentially causing misalignment in the drill bit as well. To avoid this situation, bearings are built in. Additionally, the grinding unit of the drill grinder itself also has built-in bearings. With these bearings, the grinding unit is kept sturdy, allowing for smooth rotational movement during grinding and enabling easy operation.
