Mudder 6-Piece Glass Circle Cutter Set — 2–20 mm Adjustable Circular & Pencil-Style with Automatic Oiling

The Mudder 6-piece glass circle cutter set is a compact toolkit for scoring and cutting round or straight lines in 2–20 mm glass using carbide heads, a pencil-style cutter with automatic oiling, and an adjustable circular cutter.

This kit brings together precision carbide cutting wheels, an ergonomic alloy handle, and an adjustable circular guide so you can make consistent circular cuts and controlled straight scores for hobbies, small repairs, and craft projects. The set includes multiple cutter head sizes plus accessories to maintain and align blades, making it useful for mosaics, stained glass, mirror trimming, bottle cutting and other hands-on glass work.

How does the circular cutter create accurate round cuts?

The adjustable circular cutter uses a central pivot and a soft rubber centre to stabilise the tool while you rotate it around the glass, producing even, repeatable circles. It’s designed for a full range from small to larger diameters, so you can match the circle size to your project needs.

• Adjustable arm spans typical craft sizes up to about 30 cm (11.8 in).
• Rubber centre reduces slippage and keeps the pivot steady.
• Carbide cutting head delivers a sharp, consistent score for clean breaking.
• Lightweight construction for controlled, single-handed rotation.

What features help with precise straight-line and detailed cutting?

The pencil-style cutter in this set is built with an automatic oil dropper that lubricates the wheel during use, reducing friction and smoothing the scoring action. Its slim, pen-like design gives you fingertip control for detailed patterns, tight curves, and delicate trimming.

• Pencil form factor for fine control around small shapes and edges.
• Automatic oiling keeps the cutting wheel lubricated for smoother scores.
• Interchangeable carbide heads in multiple sizes for varied line widths.
• Screwdriver and spare parts included for quick on-site adjustments.

Which glass thicknesses and materials can this set handle?

This Mudder set is intended for glass pieces from 2 mm up to 20 mm thick, covering a broad range of craft glass, mirrors, and some bottle or tile applications. It’s best suited to scoring and then separating the glass using proper breaking techniques rather than attempting heavy industrial cutting.

• Suitable for 2–20 mm glass thickness range.
• Works with stained glass, mirrors, tiles, and bottles for DIY projects.
• Carbide wheels sized for fine to larger scores (approx. 2–20 mm adaptability).
• Not intended for tempered glass or heavy structural glass without specialist tools.

Who this is for: Makers, hobbyists, and home DIYers who want a compact, versatile glass-cutting kit for crafts and small repairs will find this Mudder 6-piece set helpful. It’s designed for people comfortable with hand tools who follow safe glass-handling and breaking methods. If you need a portable set with multiple wheel sizes, an adjustable circular guide, and basic maintenance tools in one package, this product is a practical choice.

Safety reminder: always wear eye protection, cut on a stable flat surface, keep pointed components away from children, and follow recommended scoring-and-breaking steps for clean results.
