6 in. x 4-1/2 in. 3/8 in. Radius, 3/4 in. Depth, 7/8 in. Width, Big Bit Bronze Groover (Wood Handle) - KRAFT

Professional-grade bronze hand groover featuring an extra-wide 7/8-inch bit for cutting substantial control joints in concrete slabs. Manufactured by Kraft Tool Company with traditional wood handle for superior control during concrete finishing operations. The combination of 3/4-inch depth and 7/8-inch width creates pronounced control joints ideal for thicker slabs and commercial applications requiring highly visible joint lines.

FEATURES AND BENEFITS

3/4-Inch Depth Bit: Cuts control joints to proper depth for 4-6 inch concrete slabs (approximately 1/4 to 1/3 slab thickness)

3/8-Inch Radius Profile: Creates clean grooves with slightly rounded edges that resist chipping

Premium Bronze Construction: Durable bronze blade breaks in smoothly and provides excellent concrete release with minimal sticking

6" x 4-1/2" Blade Size: Provides excellent control and stability for precise joint cutting

Traditional Wood Handle: Comfortable grip reduces hand fatigue during extended finishing work
