Tork Craft Mini Engraving Cutter 0.8Mm Rev. Taper 2.4Mm Shank

Description

Shape: 0.8mm Reverse Taper
Tip Diameter: Ø1.6mm
Shank Diameter: Ø2.4mm

This Mini Engraving Cutter is a specialized precision tool featuring a unique 0.8mm reverse taper head. Unlike
standard cylindrical or ball bits, the reverse taper—or ‘inverted cone’—shape is wider at the tip than at the base.
This specific geometry is indispensable for undercut techniques, allowing you to create crisp, flat-bottomed grooves
and sharp internal angles that are difficult to achieve with rounded tools.

The ultra-fine 0.8mm diameter of the head makes it a premier choice for micro-detailing and high-precision etching.
It is particularly effective for ‘setting’ seats for small stones in jewelry or cleaning up tight corners in
intricate carvings. Because the wider tip provides a distinct edge, it allows for incredibly clean starts and stops
when engraving fine text or geometric patterns into hardwoods and precious metals.

To ensure professional-grade stability, the cutter is integrated with a 2.4mm shank. This robust shank size provides
the necessary rigidity to support the delicate 0.8mm tip, significantly reducing the risk of snapping under lateral
pressure. It fits seamlessly into most standard rotary tools and high-speed engravers, ensuring a concentric,
wobble-free rotation that is vital when working at a microscopic scale.

Durability and precision are the hallmarks of this cutter’s construction. Built to maintain its sharp profile even
through repetitive use on tough surfaces, it offers the consistency required for professional-tier craftsmanship.
Whether you are a master jeweler, a watchmaker, or a dedicated hobbyist, this reverse taper bit provides the
architectural control needed for the most demanding detail work.

The shank is securely locked in place by fitting
it in the corresponding collet or making use of a keyless chuck.

For improved accuracy, make use of a flexible
shaft connected to the rotary tool.

Rotation speed:

Most rotary tools have the benefit to adjust the rotation speed. Many tool bits that fit in rotary tools have a maximum speed setting. This can normally be found on the packaging.

All materials react differently to speed and will need the tool bit to rotate slower.
It is recommended to start using accessories on the slower speed first, before increasing the speed as needed.

The diameter of the tool bit fitted also determines the rotation speed. The larger the diameter, the slower the speed. If the speed is set too high, it could bend the shank/shaft resulting in injury.
