BURMONG 3-Piece Sphere Rotary Burr Set
The BURMONG set includes three sphere burrs: 25mm, 30mm, and 40mm diameters, all with 5/8″-11 universal threads. These burrs are made from high-density carbon steel and can handle speeds up to 12,000 RPM, making them suitable for rapid hollowing and shaping in wood. Best for beginners and seasoned turners who want progressive sizing for bowls, interior contours, and detailed hollows. Better for dry work, with direct compatibility on standard angle grinders for steady operation across speed ranges. A caution: carbide teeth are aggressive; use light passes to avoid tear-out in fragile woods.
Why chosen: Direct grinder compatibility reduces setup time, and the three sizes enable a stepwise approach from rough carving to fine detailing. This set excels for bowl interiors and decorative hollows where consistent surface finishes are desired.
- Directly mounts to 4.5″ & 5″ angle grinders
- Hundreds of precision carbide teeth deliver efficient material removal
- 360° cutting action supports complex curves
Best for: Woodturners and hobbyists who want fast hollowing with adaptable diameters. Avoid this if you are working with very hard woods or if you require delicate, ultra-fine inside finishes without controlled feed rates.
KATA 8PCS Hole Saw Kit
The KATA set features 8 hole saws ranging from 1″ to 2-1/8″ (25–54 mm), plus mandrels and a hex key for easy installation. Made from heat-treated carbon steel with a durable black coating, these saws are designed for fast, clean cuts in soft wood, thin PVC, and plywood. Best for DIY projects and quick interior cutouts where straight, accurate holes are required. A limitation: not designed for metal or very hard woods, and larger diameters require stable backing to avoid breakout.
Why chosen: The kit covers common interior hole sizes for hollowing projects, with a case for portability and quick swap between diameters. Choose this if you need multiple hole sizes in one bundle for wood turning and interior shaping.
PETUOL Hole Saw Set, 22PCS
The PETUOL set includes 22 pieces, with sizes from 3/4″ through 5″ (19–127 mm), two mandrels, drill bits, a hex key, and a storage box. The blades are made from premium heat-treated carbon steel with anti-oil and anti-rust features, designed for durable performance in soft wood, plywood, and drywall. Best for woodworkers who want an all-in-one kit with storage and easy replacement parts. A caution: not intended for hard materials or metals; ensure proper backing to prevent tear-out on thin stock.
Why chosen: Broad size range supports a wide array of hollowing tasks from small interiors to larger cavities. Good for users who value organized storage and straightforward tool changes.
BURTOK Upgrade Bushcraft 10″ Hand Auger
While not a traditional hollowing tool in a turning sense, the BURTOK auger is designed for efficient interior drilling in wood for bushcraft and outdoor tasks. It features a welded stainless and high-carbon steel construction, a thicker Scottish eye at 1/8 inch, and a 12-inch length capable of drilling 1-inch holes to a 9-inch depth. Best for campers and outdoor enthusiasts who require quick, sturdy interior bores. A caution: not optimized for intricate hollowing or high-polish interior finishes; better for larger, simple cavities.
NEIKO 02604A Hole Punch Set
The NEIKO kit offers 14 hollow punch heads (3/16″ to 1-3/8″ and 5–35 mm), plus a 6″ handle with built-in center punch. It’s designed for gasket cutting, leather, foam, and thin materials. Best for woodworkers who also do related crafts requiring accurate round cutouts. A caution: primarily a punching tool set, not a traditional hollowing cutting set for deep interior woodwork; may require compatible backing surfaces for clean finishes.
Buying Guide
What type of hollowing task are you planning?
For interior contouring and bowls, sphere burrs like the BURMONG set offer aggressive material removal with precise sizes. For deep hollowing with stable control, opt for long-handle hollowing tools from Easy Wood Tools. If you need quick, multiple hole sizes, hole saw kits from KATA or PETUOL are ideal.
Which tool material matters?
Carbide-based teeth and carbon steel bodies provide different life and cutting geometry. Carbide teeth excel in dense or resinous woods, while carbon steel handles general-purpose use with accessible replacement parts.
Is direct grinder compatibility important?
Yes. The BURMONG sphere burrs fit 5/8″-11 threads on standard angle grinders, reducing setup time and enhancing stability. Direct mounting is beneficial for vibration control during aggressive hollows.
What about ergonomics and safety?
Long-reach hollower tools (like some Easy Wood Tools models) reduce hand fatigue during extended sessions. Always use appropriate PPE and maintain blade/bit control to avoid tear-out on thin or open-grain wood.
Budget and versatility considerations
Combination sets (hole saws plus hollowing tools) provide broad versatility for a single project. If your work is mostly hollowing bowls, prioritize hollowing tools with stable handles and carbide cutters. If you frequently create interior holes, a comprehensive hole saw kit adds value.
Maintenance tips
- Keep blades and cutters clean and dry after use.
- Sharpen or replace worn teeth to maintain clean cuts.
- Use light passes to minimize chipping on soft woods and avoid tear-out.

FAQ
What is the best tool for beginners hollowing wood?
The BURMONG Sphere Burr Set provides a straightforward entry with three sizes and direct grinder mounting for quick setup.
Which hollowing tool offers the longest reach?
The Easy Wood Tools Pro Easy Hollower provides the longest reach among the listed hollowing tools, aiding larger interior work.
Can hole saws be used for wood interior boring?
Yes, hole saws are suitable for soft wood and thin plywood, enabling clean interior cutouts when backed properly.
Are carbide cutters necessary for hollowing?
Carbide cutters often offer better wear resistance and cleaner finishes, especially in resinous woods, though they can be pricier.
Should I buy a mixed kit or separate tools?
If you need breadth (multiple hole sizes plus hollowing tools), a mixed kit is cost-efficient. For focused hollowing, prioritize hollowing tools first.
What safety precautions are essential?
Wear eye protection, use clamps or a stable workstation, and feed cutters slowly to avoid tear-out and kickback.
