This jobber-length, straight-shank twist drill uses a 135° split point to help start holes more accurately. It’s a solid pick for drilling stainless steel and other metals, while also being suitable for materials like aluminum, copper, plastics, and wood.
What’s included & sizing: You get 1 drill bit with a 9mm cutting diameter, 67mm (2.64 in) flute length, and 124mm (4.88 in) overall length.
Tip for best results: Keep the drill at a 90° angle to the workpiece, and slow down as material hardness increases—adjusting speed can improve cutting efficiency, reduce damage, and help the bit last longer.
