Makita B-28597 Impact Gold Magnetic Screwdriver BIT SET Holder Torsion 1/4" HEX

Impact Gold Torsion Bits feature a unique design which focuses the forces exerted on a regular screw bit away from the tip,

 meaning less chance of breakage. Impact Gold Torsion bits can last up to 10x longer than a regular screw bit,

 whilst an Impact Gold Insert bit can last up to 15x longer than a regular bit when coupled with a holder.
