Round edges + carve flowing hollows
The Kutzall 1/4″ Shaft Ball Nose Burr combines straight sides with a rounded end, giving you two useful ways to approach power carving. Use the sides to level surfaces and round over edges, then work with the rounded end to hollow concave forms or carve grooves with a curved bottom. It is a versatile profile for woodcarving projects that move between flat areas and inward curves.
The 1/4″ shaft fits a matching collet or compatible adjustable chuck on a die grinder or flex-shaft handpiece. Match the head size to the space you want to carve, and check your power tool’s mounting and speed limits before use.

Mounting Guide
- Match your shaft size
Use a 1/4″ collet or compatible adjustable chuck on a suitable rotary tool, die grinder or flex-shaft handpiece. Hand drills and drill presses are not recommended.
- Seat the shaft securely
Insert at least half of the shaft into the collet or chuck. Secure it according to your power tool’s instructions.
- Use the recommended speed
Recommended operating range: 15,000–30,000 RPM. Both material-removal rate and control improve as speed increases toward the burr’s recommended operating range. Never exceed the lowest maximum speed rating in your setup. Use light pressure and let the tool do the work.
- Let it stop completely
Let your power tool stop completely before setting it down.
Caring for your Kutzall
Brush away buildup
A few passes with a soft wire brush help clear material from between the teeth.
Clear stubborn residue
A torch can remove stubborn buildup from the metal working surface. The tungsten-carbide teeth tolerate the heat.
Protect the teeth
Kutzall’s tungsten-carbide teeth are securely brazed to the steel tool with a nickel alloy. Protect the teeth from impact against hard surfaces, especially while spinning. Let your power tool stop completely before setting it down.
Not for use on metals, ceramics or hard stone.
More on tool careLet the tool cool before handling. Keep heat away from handles and other non-metal components.

- RGRamon G.Verified BuyerReviewing1/4" Shaft - Ball Nose Burrs - 1/2" x 1-1/2" CoarseI recommend this productRated 5 out of 5 stars7 months agoExcellent performance.
I'm finishing a Maloof inspired nanny rocker which is due to go on tour exhibitions starting the month of May 2026 extending up to 2027. I've use your ball nose burr in my die grinder and attached it to a 1/4" flex shaft to tight places. Exhibition rules prohibit views prior to showing dates. Hopefully Later I can upload a few pics next year.
Thanks again
