⚡ At a Glance
- • Cutting Quality: Dual-edge two-flute design, smooth countersinks and reduced chatter
- • Best for: DIYers and woodworkers needing quick, clean screw holes
- • Not ideal for: Extended heavy-duty work in hardwoods
Titanium-coated high-speed steel countersink bits use a dual-edge two-flute design and an 82-degree angle for fast, clean cutting. The kit includes spare tips, a 60mm magnetic extension holder and a storage case.
Faster, cleaner cuts – thanks to dual-edge two-flute design
Two cutting edges slice wood with reduced vibration, eliminating the chatter common to single-blade bits. The stepped chamfer profile lowers cutting resistance for smoother chip removal.
Quicker countersinking and neater finishes mean fewer sanding or rework sessions, so screw fittings look professional with less effort.
Accurate screw seating – with an 82-degree countersink angle and stepped chamfer
An 82-degree angle matches common screw heads for a snug recess, while the stepped chamfer controls depth and prevents overcutting. Adjustable depth settings let the pilot and countersink operate in one pass.
Screws sit flush and hold securely, reducing the need for fill or head damage during assembly.
Workshop-ready versatility – with 1/4" hex shank and replaceable bits
A 1/4" hex shank fits standard chucks and quick-change holders, compatible with impact drills and bench drills. The set supplies five replaceable drill tips alongside countersink cutters and a magnetic 60mm extension.
Quick bit swaps and broad tool compatibility keep the job moving, and spare tips extend usable life without hunting for replacements.
