## Summary description

Proxxon 28758 is a single milling drill bit with a 1 mm diameter designed for drilling and milling operations. Intended for precision work, this 1 pc tool suits model making, fine metal or PCB work, and small workshop tasks. Compatible with rotary tools and drills that accept small-diameter bits; use according to safety and tool specifications.

## Long description

Proxxon 28758 is a single milling drill bit with a diameter of 1 mm supplied as one piece. Manufactured from solid tungsten, this double-flute cutter has a fishtail profile that allows cutting to the centre for boring and clockwise cutting. The 2.35 mm (7/64") shank fits standard small-tool chucks and is intended for precision tasks such as model making, fine metalworking, engraving and milling of circuit boards. The cutter is compatible with rotary tools and micro mills that accept small-diameter bits, including the Micro Mill MF70, Micro Miller FF230 and Mill/Drill Head PF230.
Advantages
The solid tungsten construction provides wear resistance and edge retention for small-diameter milling and drilling. The double-flute design and fishtail profile enable centre-cutting and controlled chip evacuation during clockwise rotation. Its small 1 mm diameter delivers precise results in fine-detail applications while the 2.35 mm shank ensures secure clamping in common micro-tool collets and chucks.
Suitable for
 Model making and scale parts
 Engraving and precision milling
 Circuit board (PCB) milling and drilling
 Fine metalwork on steel, brass and aluminum
 Machining plastics, composites and glass (with appropriate speeds and care)
Key specifications
 Cutting diameter: 1 mm
 Number of pieces: 1
 Material: solid tungsten
 Flute type: double-flute, fishtail profile, centre-cutting
 Cutting direction: clockwise
 Shank diameter: 2.35 mm (7/64")
 Compatible tool types: rotary tools, micro mills and mill/drill heads that accept 2.35 mm shanks
How to use
Install the 2.35 mm shank securely in the tool chuck or collet, ensuring concentric clamping and adequate tightening. Select appropriate spindle speed and feed for the work material: use higher speeds with light feed for plastics and PCBs, and moderate speeds with gentle feeds for metals. Operate with clockwise rotation and avoid axial overload; use light passes for precise depth control. Keep the workpiece secured and use coolant or air blast where suitable to remove chips and reduce heat when machining metals or composites.
Usage recommendations
Use appropriate personal protective equipment and observe machine safety. For brittle materials such as glass or carbon fiber, reduce feed and use steady support to prevent chipping. When milling PCBs or delicate parts, start with test cuts to determine optimal speed and feed for clean results.
