EXO stone carving burr cone 4.4 mm / 16 mm for sandstone, EXO 141066

EXO stone carving burr cone 4.4 mm / 16 mm is a rotary carving tool designed for work on sandstone. The cone-shaped head and 16 mm working length offer controllable contact area for shaping, carving, grooving and surface finishing. With a 4.4 mm shank, the burr fits most standard rotary tools and die grinders for masonry detailing, restoration and craft projects that require precise removal of soft stone material.

Advantages

The cone geometry provides a gradual cutting profile that allows smooth transitions between surfaces and accurate depth control. The tool is optimized for sandstone, offering effective abrasion on softer stone without excessive chipping. Its standardized shank diameter ensures compatibility with a wide range of rotary tool collets and chucks, simplifying tool changes. The compact working length and tapered head improve access to narrow or recessed areas for detailed work.

Suitable for

• Shaping and profiling sandstone elements
• Carving decorative details and lettering in soft stone
• Grooving and undercutting for restoration or joinery
• Surface texturing and smoothing of masonry components
• Modeling and craft projects that use sandstone or other soft sedimentary stone

Key specifications

• Head shape: cone
• Shank diameter: 4.4 mm (fits common rotary tool collets)
• Working length (head): 16 mm
• Material suitability: sandstone and other soft stone
• Application type: shaping, carving, grooving, surface finishing

How to use

Secure the 4.4 mm shank in the rotary tool or die grinder collet and tighten according to the tool manufacturer's instructions. Start at low to moderate speed and make progressive passes, allowing the burr to remove small amounts of material to avoid overcutting. Use light pressure and steady movement to maintain control and prevent undesired chipping. For fine details, reduce speed and use short, controlled strokes; for larger shaping work, increase speed gradually while maintaining safe handling practices. Wear appropriate personal protective equipment such as eye protection, dust mask and hearing protection when machining stone.

Usage recommendations

For best results on sandstone, work with multiple shallow passes instead of a single heavy cut, keep the burr clean of clogged debris, and monitor tool speed to match the hardness of the stone. Use water dust suppression or local extraction when possible to reduce airborne dust during extended use.
