FTG USA #10 (3/16") Wood Countersink Drill Bit 3-Pc Set — 1/4" Hex Shank & Adjustable Depth Stop

The FTG USA #10 (3/16") Wood Countersink Drill Bit 3-Pc Set is an adjustable pilot-drill and countersink combo that drills, countersinks, and counter-bores in one pass for clean screw seating in soft and hard woods.

This three-piece kit combines a tapered 3/16" (sized for #10 screws) pilot drill with a four-flute countersink cutter machined from #45 carbon steel and high-speed M2 steel components. Each bit mounts on a 1/4" quick-change hex shank for fast swaps with impact and quick-change chucks; a small hex key secures the adjustable depth stop so you can set consistent countersink depth for flush or slightly recessed screw heads. Designed by FTG USA and manufactured to spec, the set is built to speed woodworking tasks from cabinetry to deck trim without multiple tool changes.

How does this set save time on drilling and countersinking?

Instead of drilling a pilot hole, then changing bits to countersink and counter-bore, this set completes all three operations in one pass. The tapered drill creates an accurate pilot profile while the four-flute countersink cutter shapes a clean 82° chamfer for standard screw heads.

• One-step pilot hole, countersink, and counter-bore action.
• Wide flute design for faster chip evacuation and reduced clogging.
• 1/4" hex shank fits quick-change and impact drivers for rapid bit swaps.
• Adjustable depth stop locks with included hex key for repeatable recess depth.

Will these bits work in hard woods and with different screw sizes?

The FTG USA set is engineered to handle both soft and hard wood thanks to the strong cutter geometry and M2/HSS taper drill. While optimized for #10 screws (3/16" drill size), the adjustable depth control and tapered pilot accommodate a range of screw lengths by altering the stop position.

• 82° countersink angle matches common screw head profiles.
• Tapered pilot tip reduces tear-out in hardwoods and plywood.
• Replaceable taper drills available for extending service life.
• Suitable for wood plugs up to 3/8" where concealment is needed.

How do you set and maintain consistent countersink depth?

Set the flat on the shank against the hex screws on the depth collar and tighten the included hex wrench to lock the desired depth. This mechanical stop prevents the cutter from plunging further once the chosen recess depth is reached, giving repeatable results across multiple fasteners.

• Depth collar attaches to shank with two hex screws for secure indexing.
• Hex wrench included for quick adjustments on the job site.
• Laser-printed brand logo aids quick identification in toolkits.
• Durable cutter steel resists dulling with normal woodworking use.

What driving tools and accessories are compatible with this set?

The bits feature a 1/4" quick-change hex shank so they are compatible with impact drivers, compact drills, and standard quick-change chucks. FTG USA also offers storage containers and replacement tapered drill bits if you want an organized kit or spare cutting tips for long-term use.

• Fits 1/4" quick-change chucks and most magnetic bit holders.
• Impact-rated hex shank designed for high-torque applications.
• Optional storage case available as a bundle add-on on the product page.
• Replacement taper bits sold separately to extend tool life.

Who is this for: Woodworkers, finish carpenters, cabinetmakers, and DIYers who want an efficient, repeatable way to drill pilot holes and seat screw heads perfectly. The FTG USA 3-piece set suits professionals wanting a fast-change solution in the field and hobbyists aiming for cleaner finishes without switching bits between steps.
