Until you try them, you won’t believe that a forstner bit can be this inexpensive and still perform this well. CMT resharpens top quality imported bits in their own Italian factory. That results in a top quality forstner bit at an affordable price. Guided by the rim rather than a center spur, Forstner bits bore flat bottomed holes which may be overlapped or may enter at odd angles. Use caution with small bits (3/8" to 5/8") because they do not have a great deal of space available for chip ejection. Bits over 7/8" have a saw tooth rim for improved performance. Made of High-Speed Steel, these bits stay sharp, and stay sharp longer than bits made of ordinary tool steel. Blanks are made in China.
