Precision Countersink Drill with Depth Stop

The screw does not sit flush and the surface tears when drilling.

Anyone who needs precise countersinks for wood joining knows the problem: the drill goes too deep, the material splinters, and the screw sits crooked or protrudes. The precision countersink drill bit from Sovora supports clean countersinks with an adjustable depth stop that can limit the chosen drilling depth – for flat-bottomed holes where screw heads can be flush or recessed. Less rework, lower risk of tear-out, and more control when drilling.

Advantages

• No more overdrilling: The adjustable depth stop helps maintain the desired drilling depth – you need to check the depth less frequently while drilling.
• No time-consuming rework: The two-edge design supports clean edges and even material processing – reducing additional grinding effort.
• No worries about premature wear: The cutting tip made of hardened steel is designed for regular use and supports long-lasting performance when used properly.

Specifications

• Number of cutting edges: 2 cutting edges
• Depth stop: Adjustable with scale and limit ring
• Fastening: Hex screw locking system
• Cutting head material: Premium hardened steel
• Compatibility: Hand drills, drill presses, screwdrivers
• Suitable materials: Wood, plastics
• Variants: Red, Gold, Blue

Application

1. Set depth: Slide the limit ring to the desired drilling depth and secure it with the hex screw.
2. Drilling: Place the countersink drill bit on the marked spot and drill with steady pressure – the depth stop helps ensure controlled drilling to the set depth.
3. Insert screw: Insert the screw into the finished countersink – for a flush or recessed fit of the screw head.

Pro tip: First test the set depth on a scrap piece of the same material – this ensures the countersink matches the screw head diameter exactly before working on the actual workpiece.
