Freud 12-150: 23/32″ Double Flute Straight Bit
This 23/32″ straight bit is designed for clean cuts in solid wood, plywood, and composites. It features two carbide-cutters and a 1/2″ shank, with an overall length of 2-7/8″ and carbide height of 1-1/4″. Best for woodworkers needing precise dado bottom textures in a wide range of materials. It’s a solid choice for cabinet-making and edge-profile work where clean shoulders matter.
Best for: Enthusiasts and professionals who prioritize clean edge quality and compatibility with standard 1/2″ collets. Caution: If your setup requires a longer cutting length for deep dados, verify clearance first.
Freud 16-103 23/32″ Mortising Bit
This 23/32″ mortising bit is suited for mortise and tenon work, offering reliable cuts across plywood, hardwoods, and softwoods. It can be used with CNCs, table-mounted routers, handheld routers, or automatic machines, providing versatility in a shop setting. Best for: Projects requiring robust mortises and snug joints, particularly in cabinetry and framing.
Limitation: The 1/4″ shank may require appropriate adapters or collets on some machines; verify compatibility with your router.
Yonico Router Bits Dado Straight Bit Undersize 23/32″ 1/2″ Shank
The Yonico 23/32″ dado bit is tailored for creating dado grooves to fit 3/4″ plywood panels. It uses a 1/2″ shank and premium C3 micro-grain tungsten carbide blades for a sharp, long-lasting edge. Best for: Precision dado work in cabinet sides, shelves, and paneling where exact panel fit matters. Caution: Check that the undersized cut diameter matches your plywood thickness for a precise joint.
Yonico 14924: Dado Straight Bit Undersize 23/32″ 1/2″ Shank
This undersized 23/32″ bit is ideal for making dado grooves sized to receive dressed plywood, particularly when a snug fit is essential. It includes a 1/2″ shank and relies on premium micro-grain carbide to maintain edge life. Best for: Dado grooves that require tight tolerances in 3/4″ plywood panels. Limitation: The undersized diameter requires careful measurement to avoid oversized joints.
Bosch 84602MC 23/32″ Plywood Mortising Bit
Designed for undersized plywood mortises, this Bosch bit features micrograin carbide-tipped geometry for smooth cuts and wear resistance. It is tailored to match 3/4″ plywood thickness, supporting tight joints in cabinetry and furniture. Best for: Standard plywood mortises where clean, consistent holes are required. Limitation: Only as effective as the router’s stability; wobble can affect mortise squareness.
Aoranto 4-Piece Undersize Dado Bits Set
This set includes four straight router bits with cutting diameters of 7/32″, 11/32″, 15/32″, and 23/32″ on 1/4″ shanks. It is crafted for undersized plywood dado work across multiple thicknesses. Best for: Versatile dadoing in hobby projects where multiple groove sizes are needed. Caution: The 1/4″ shank may limit use with larger collets on some routers that require 1/2″ shanks for rigidity.
Buying Guide: 23/32″ Router Bits
What to consider when selecting a 23/32″ bit
- Material compatibility: Choose bits with carbide tips for durability on hardwoods and plywood.
- Shank size: A 1/2″ shank provides rigidity; some machines require adapters for smaller shanks.
- Undersized vs standard diameter: Undersized bits are designed to match plywood thickness more precisely, improving joint fit.
- Cutting length: Longer cutting lengths handle deeper slots; shorter bits can be more maneuverable in tight spaces.
- Usage type: Mortising bits are separate from generic straight bits; ensure the bit matches your project (dadoes vs mortises).
Frequently Asked Questions
- What is a 23/32″ dado bit best used for? – It’s ideal for creating dados and grooves to fit 3/4″ plywood panels in cabinetry and shelving.
- Why choose an undersized 23/32″ bit? – Undersized bits help achieve precise plywood dado joints by compensating for plywood thickness tolerances.
- Can I use a 23/32″ bit with a router that has a 1/4″ collet? – You will need a 1/2″ to 1/4″ shank adapter, but using the correct collet size is recommended for optimal rigidity.
- Are carbide-tipped bits worth it for plywood? – Yes. Carbide tips provide longer edge life and smoother cuts in plywood and composites.
- What should I consider when choosing between dado and mortising bits? – Dado bits are for straight grooves; mortising bits produce deeper, square holes for joints. Choose based on the joint you plan to create.
- Is there a risk of tear-out with 23/32″ bits? – Tear-out risk exists in under-supported edges; use clamping and climb cutting techniques when appropriate.
