The all-metal construction is built to withstand heavy daily use on the jobsite. At 10.5 inches in length and 1.09 pounds, it is a compact, durable accessory that extends the utility of an existing spline drive rotary hammer without requiring a separate dedicated tool. Licensed contractors and trade professionals use this adapter to expand their bit inventory compatibility on active job sites.\u003c\/p\u003e\u003cp\u003eThis adapter is suited for professional use in construction, demolition, and concrete drilling applications where a spline drive rotary hammer is the primary tool. It is particularly useful when a crew already has a stock of B taper bits and wants to avoid duplicating tools. The adapter fits into the spline drive chuck and accepts standard B taper shank bits, making it a practical solution for residential and commercial jobsites alike.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eConverts a spline drive rotary hammer to accept B taper shank bits\u003c\/li\u003e\n\u003cli\u003eAll-metal construction rated for heavy daily jobsite use\u003c\/li\u003e\n\u003cli\u003eCompact profile at 10.5 inches long and 1.55 inches wide\u003c\/li\u003e\n\u003cli\u003eLightweight at 1.09 pounds for easy handling\u003c\/li\u003e\n\u003cli\u003eSold individually — one adapter per unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with spline drive rotary hammers that accept B taper shank bits.
