One bit that does it all. Drill, Counterbore, and Countersink in a single operation. Countersink Drill Bits are a high-quality solution when you need to drill, counterbore, and countersink a hole quickly and accurately.
PRODUCT DESCRIPTION
Self-clearing
Drill bits are precisely fit into the countersink sleeves and the two chamfered flutes enable the faster operation and self-clearing drilling on the swarf, making perfectly sized and shaped holes.
Adjustable countersunk head hole
Also, Countersink Bits For Wood - The Adjustable Stop Collar allows you to adjust the Counterbores depth and Adjustable Cutters can be adjusted for many screws sizes.
Perfect your carpentry
The 2 in 1 design turns two-step countersinking into a one-step operation. This can make perfect countersink holes for both flush-set and plugged screws, without splitting the wood and enjoying neat projects with drill bit sets.
Sharpness, Accuracy, and Concentricity
This precision countersink with properly-centered drill bits, an adjustable cutter counterbore, and a sharp point tip, allows for extremely high accuracy andprevents marking of the workpiece. Our countersink drill bits have been extensively tested to ensure the highest possible quality.
Extensive use
The countersink bits are ideal for bench drill, hand drill, and a conventional electric drill, perfect for wood, fiberboard, particleboard, plywood, plastic, PVC, rubber, etc.
Tips
Make sure you are consistently drilling straight to avoid breaking bit and pick the drill in and out of the hole to avoid loading up the bit with chips.
It is recommended to use a center punch to position a starting point, preventing the drill bit from wobbling on the workpiece.
Every time smoke develops on a drilling operation (typically happens when drilling on hard timber), please stop and clear the swarf off the drill bit. You might need to stop and clean it several times.
The best practice is to adjust all your settings (drill bit size, countersink size, depth stop location) and make a test drill into a piece of scrap before drilling the real workpiece.
