Tool Holder Blanks
Tool holder blanks have the taper "finished" (hardened, ground, etc.), but leave a large unfinished portion that can be machined to your requirements.
TAC Rockford stocks hundreds of sizes in virtually all common taper standards and sizes.
Need something you don't see on our site? No problem! We offer custom-made blanks to meet your needs. Also, we often have additional sizes in stock not listed on our website.
