Three-Rake Drill Grinding Machine EDSG-313
A three-flute drill grinder for diameters ranging from 3 millimeters to 13 millimeters. Anyone can easily grind to the three-flute shape using the Nachi SG-ESS drill.
The Fastex Three-Rake Drill Sharpener EDSG-313 is a revolutionary drill sharpening machine that can grind drills from 3mm to 13mm into a three-rake shape, ensuring consistent results whether operated by a novice or an experienced user. It sharpens drills with a three-rake design, which is also adopted by the Nachi SG-ESS drill. The three-rake shape is a thinning design for drills without a chisel tip, offering excellent concentricity and high drilling precision. However, due to chipping issues, it is not suitable for carbide drills. The sharpening method involves holding the drill in a collet-equipped holder for positioning, and then setting the sharpening unit to match the drill diameter. After that, simply inserting the drill into the sharpening unit will grind it into the three-rake shape. The holder, equipped with our unique patented bearing technology, prevents collet wear, eliminating concerns about drill misalignment. It allows for the easy regeneration of broken drills and those with diminished cutting performance that are not being used in the factory, contributing to cost reduction within the company. Note: Drills that are broken and lack a groove, or those that are too short to be grasped by the collet, cannot be sharpened. [For more details, please refer to the catalog.]

Detailed information
-
Three-Rake Shinning Shape Three-Rake Shinning features a cutting edge without a chisel, providing excellent bite and superior centripetal characteristics. It is an optimal shinning shape for high-speed drilling operations that require precision.
-
Prevents wear of the collet with built-in bearings. When tightening the collet, the collet holder is subjected to very strong forces, 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 sharpener itself also has built-in bearings, which help maintain the durability of the grinding unit and allow for smooth rotational movement during grinding, enabling easy operation.
