Woodworking Plug Cutters – Straight & Tapered Sets

Plug Cutters for Clean, Seamless Screw Concealment

Plug cutters let you mill your own wood plugs from matching scrap or contrasting stock, producing a far cleaner result than pre-made dowels or putty. A tapered plug cutter creates a slightly conical plug that wedges tightly into a counterbored hole, while a straight plug cutter produces a cylindrical plug ideal for longer, dowel-style fills.

Choosing between straight and tapered designs comes down to the joint type and depth. For through-holes or deep counterbores where you need extra length, an extra-long dowel plug cutter set provides the reach standard cutters cannot. For furniture work where a flush, grain-matched surface is the goal, tapered plug cutters from the 8-piece plug cutter & tenon set deliver a tight, pop-out-free fit.

Plug cutters are used in a drill press at low speed for the cleanest results. Secure the workpiece firmly, run the cutter perpendicular to the grain of your plug stock, then snap the plug free with a screwdriver. Grain orientation in the plug should match the surrounding surface to minimize visibility after finishing.

Straight vs. Tapered Plug Cutters: Which Should You Choose?

Tapered plug cutters are the most popular choice for face-frame cabinetry and furniture because the slight taper creates a mechanical lock in the hole, eliminating gaps. Straight cutters are better suited for long face-grain plugs and production work where speed matters. The Make It Snappy tapered plug cutters are compatible with standard drill bits for a matched counterbore-and-plug system.

Frequently Asked Questions

What is a plug cutter used for in woodworking?

A plug cutter is a cylindrical drill-press bit that cuts small wooden plugs from solid stock. These plugs are used to conceal counterbored screw heads, producing a cleaner surface than wood filler or putty.

What is the difference between a straight and tapered plug cutter?

A straight plug cutter produces a cylindrical plug with parallel sides, suitable for long counterbores and dowel-style fills. A tapered plug cutter produces a slightly conical plug that wedges tightly into a standard counterbored hole, creating a more secure fit with less chance of the plug popping out.

Can I use a plug cutter in a hand drill?

Plug cutters are designed for use in a drill press, which provides the perpendicular, wobble-free rotation needed for clean, concentric plugs. Using one in a handheld drill risks off-center cuts, torn grain, and tool damage.

What drill bit size do I need to pair with a tapered plug cutter?

The pairing depends on the plug cutter's listed diameter. Most tapered plug cutters specify the matching counterbore bit size — the Make It Snappy tapered plug cutters are designed to pair with standard drill bits from the same system for a matched fit.

How do I remove a plug cutter plug without splitting it?

After cutting, slide a flathead screwdriver or thin chisel into the kerf alongside the plug and gently lever it free. Avoid prying from the top; apply gentle lateral pressure at the base of the plug to pop it out cleanly.

What wood species should I use for cutting plugs?

Use the same species and cut from the same board as your project whenever possible. Matching grain direction and orientation minimizes visible color and texture differences after sanding and finishing. End-grain plugs are more visible; face-grain plugs blend better.

Does Infinity Tools sell plug cutter sets, or only individual cutters?

Both options are available. The 8-piece plug cutter & tenon set includes straight and tapered styles for maximum versatility, while the 5-piece extra-long dowel plug cutter set covers longer-reach applications.

What RPM should I run a plug cutter at?

Low drill-press speeds — typically 500 to 1,000 RPM — produce the cleanest plugs and reduce heat buildup. Higher speeds can burn the wood and dull the cutter prematurely. Consult the cutter manufacturer's guidelines for the specific diameter you are using.

Does Infinity Tools offer a price-match guarantee on plug cutters?

Yes. Infinity Tools offers price matching on eligible products. See the price-match policy page for details and how to submit a request.

How do I achieve an invisible plug after finishing?

Cut the plug from the same board used for the project, orient the grain to match the surrounding surface, glue it in place with wood glue, let it cure fully, then pare or sand it flush before applying finish. The closer the grain and color match, the less visible the repair.
