Genuine 7/16″- 21 Threaded Shank Stop Countersink HSS 1/4″-28 Threaded Shank TSC7/16-21

Industrial stop countersinks with threaded shanks enable precision countersinking and chamfering for metalworking and assembly. These High Speed Steel tools provide secure depth control and repeatable results across production runs and shop floor operations.

Specs

Material grade: HSS

Thread type: 7/16 inch-#21 threaded shank; 1/4 inch-28 threaded shank

Features

Depth control: Depth stop maintains consistent countersink depth to ensure uniform chamfers and reduce rework in metal fabrication.

Threaded shank compatibility: Two standard thread configurations (7/16 inch-#21 and 1/4 inch-28) support direct mounting in compatible tool holders, jigs, and drill presses.

Material integrity: High Speed Steel construction provides wear resistance and heat tolerance during high-speed drilling and countersinking operations.

Application scope: Suitable for drilling and countersinking metal components in automotive, aerospace, and general fabrication contexts where precise hole preparation is required.
