Sculpting with the Dremel 9954 is a breeze. Compared to Dremel's standard carving bits, this one offers remarkable material removal speed, 2X faster. Thanks to the robust stainless steel teeth, it excels in aggressive engraving and rapid material removal, while also resisting rust. The 7.9 mm wide spherical tip shape is ideal for creating intricate, rounded shapes, and when using the side of the accessory, you can tackle even larger flat surfaces and create undercuts. Please note that this accessory is not compatible with the Stylo+, Dremel Lite, and Dremel 7350.
