★ Tapered Countersink Drill Bit with Depth Stop for Wood
The Tapered Countersink Drill Bit with Depth Stop combines pilot drilling and countersinking in one operation. It consists of an HSS taper point drill, a 4-flute countersink cutter, and an adjustable depth stop collar.
The taper point drill creates the pilot hole for the wood screw, while the countersink cutter forms a recess for the screw head. The adjustable stop collar controls the drilling and countersinking depth, making the tool suitable for repetitive woodworking and assembly operations.
★ Key Features

· HSS Drill Bit – High Speed Steel construction for wood and wood-based panels.
· 4-Flute Countersink Cutter – Forms the countersink for recessed screw heads.
· Adjustable Depth Stop – Controls drilling and countersinking depth for repeated operations.
· Set Screw Adjustment – The stop collar can be repositioned and secured using a hex key.

★ How It Works
The taper point drill first creates the pilot hole. As the tool advances, the 4-flute countersink cutter removes material around the hole to create the recess for the screw head.
The depth stop collar can be repositioned by loosening the set screw with a hex key. Once set, it limits the drilling depth and helps maintain consistent results across multiple workpieces.
