DSPIAE Vigorous Sponge Sandpaper #400 (3mm) is designed for precision surface work on plastic, resin, and metal. This sponge-backed abrasive combines flexibility with durability, allowing you to achieve smooth finishes even on curved or irregular surfaces.

• Grit: #400 – ideal for intermediate smoothing and surface prep
• Thickness: 3mm sponge layer for optimal pressure distribution
• Flexible and tear-resistant construction
• Suitable for dry and wet sanding

Whether you’re refining seams, cleaning parting lines, or preparing surfaces for primer, DSPIAE sponge sandpaper delivers consistent, professional results across various modelling materials.

This versatile chamfering tool is designed for precision modifications to plastic models, featuring both inner and outer chamfering options in one compact unit.

Inner Chamfering

Includes a 90° conical bit and a 3mm spherical bit:

• The conical bit is ideal for through holes or deeper countersunk areas
• The spherical bit is better suited to shallower cavities

Both bits are constructed from forged tungsten steel, offering excellent sharpness and clean finishes.

Before and After

• Before modification – Unfinished or rough internal edges
• After modification – Smooth, refined internal chamfers

Material Quality

Forged tungsten steel delivers superior durability and sharpness for cleaner, more accurate chamfering results.

Four-Jaw Chuck

• Securely locks drill bits in place to prevent slipping during use
• Compatible with other 3mm shank tools

Outer Chamfering

Two blade sets included for 90° and 60° external chamfering on plastic rods or tubes (≤6mm diameter):

• 90° blades – Ideal for fine, precision details like muzzles or nozzles
• 60° blades – Suitable for robust shapes such as rivets, bearings, or fuel tanks

Easy Identification

• ● – Marks 3mm spherical bit and 60° blades
• ▲ – Marks 90° conical bit and 90° blades

Stable Cross Fixing

Four carbon steel blades arranged in a cross pattern ensure even, consistent beveling and stable positioning of plastic rods during chamfering.

Precision Results

• Clean 90° outer chamfering results
• Smooth 60° outer chamfering results

Thoughtful Design Features

• 1mm recessed blade placement prevents accidental contact or injury
• Embedded magnets hold blades securely during replacement and use
