This Schanbacher S 3-50 is a grinding machine designed specifically for resharpening twist drills, sometimes referred to as a drill grinder or drill bit sharpener. It is a specialist piece of workshop tooling used to restore the cutting geometry of twist drills that have become dull through use, making it a practical and cost-saving addition to any machine shop, production facility, or toolroom that relies heavily on drilling operations.
The machine accommodates twist drills ranging from 3 mm to 50 mm in diameter, giving it a broad working range suitable for both small-diameter and larger industrial drill bits. Point angle adjustment spans from 90° to 140°, and the clearance angle is also adjustable, allowing the operator to replicate precise cutting geometries across a variety of drill types and materials. According to the seller's notes, operation is described as straightforward, with the grinding motion driven by a gear motor rather than a manual mechanism.
Two motors power the machine: the grinding motor runs at 400 V and draws 0.25 kW, while a separate geared motor handling the swivelling movement runs at 400 V and 0.12 kW. The grinding wheel measures 175 x 22 x 20/90 x 20 mm. The overall footprint is approximately 810 mm wide by 570 mm deep by 1,260 mm tall, and the machine weighs around 120 kg, making it a compact but substantial benchtop or floor-standing unit.
Included with the machine are a clamping device and a presetting device, both of which support accurate and repeatable drill positioning during the grinding process. This example dates from 1987, is offered in used condition, and is currently located in Germany.
