Revolutionize your installation workflow with the Professional Quality Special 3-blade Top Sharpening Straight Bit for Switches. Specifically engineered for the rapid installation of electrical switch boxes and socket frames, this tool combines the drilling capability of a drill bit with the lateral cutting power of a router bit. Whether you are working with solid wood, PVC panels, or composite boards, this "Green Series" professional cutter ensures faster drilling, smoother cutting, and a finer finish.
Unlike standard 2-flute straight bits, our innovative 3-blade design offers superior balance and cutting efficiency. The three cutting edges engage with the material more frequently per rotation, resulting in:
Reduced Vibration: The balanced geometry minimizes chatter, ensuring a stable cut even at high RPMs.
Faster Chip Removal: Optimized gullets allow for rapid evacuation of dust and debris, preventing overheating during deep slotting.
Smoother Finish: A higher cut frequency leaves cleaner walls that require little to no sanding.
The defining feature of this bit is its Top Sharpening (center tip) design. Most straight bits struggle to enter the material vertically. However, our bit features a specialized drill-point tip that allows you to plunge directly into the workpiece like a drill. This makes it the ultimate "6-in-1 Multi-Function" tool, capable of Drilling, Slotting, Grooving, Trimming, Rebating, and Mortising without changing tools.
To ensure professional reliability, we use only the finest materials:
YG6 Tungsten Carbide Tips: The cutting edges are crafted from high-grade YG6 Native Alloy. This material provides exceptional hardness and wear resistance, keeping the edge sharp significantly longer than standard steel bits, even when cutting abrasive materials like PVC or MDF.
45# Carbon Steel Body: The shank and body are machined from solid 45# steel, offering high toughness to resist snapping under the lateral pressure of slotting.
Precision Balancing: Each bit is engineered with an offset resilience of +/- .003", ensuring concentricity for precise, wobble-free switch box cutouts.
Protective Coating: The distinctive green heat-resistant coating prevents the build-up of sawdust, resin, and pitch.
This bit is commonly referred to as the "Switch Slotting Expert."
In electrical installations, creating recessed slots for sockets and switches on wall panels or furniture can be tedious. The LAIWEI 3-Blade Bit simplifies this:
Drill: Plunge straight down to the required depth.
Move: Guide the router laterally to cut the square or rectangular shape of the switch box.
Finish: The bearing-guided versions (optional) allow you to use a template for identical, repeatable cutouts every time.
Applicable Materials:
It performs excellently on Solid Wood, Hardwood, Particle Board, Density Board (MDF), Eco-board, Plywood, and PVC plastics.
We offer multiple configurations to fit your router collet (6mm or 1/4") and project needs (with or without bearing).

Available Sizes (Shank x Cutting Dia. x Cutting Length x Total Length):
Standard Series (No Bearing):
6mm Shank: 6mm x 6mm x 25mm x 70mm
1/4" Shank: 1/4" x 6mm x 25mm x 70mm
Best for: CNC routers or freehand routing with a fence guide.
Bearing Series (Top Bearing for Templates):
6mm Shank: 6mm x 6mm x 25mm x 70mm + Bearing
1/4" Shank: 1/4" x 6mm x 25mm x 70mm + Bearing
Best for: Use with templates/jigs to cut precise switch holes repeatedly.
RPM Recommendation: Due to the long cutting length (70mm total), we recommend operating at variable speeds. Start lower and adjust based on material hardness.
Secure Clamping: Ensure the bit is inserted fully into the collet (at least 2/3 of the shank length) to prevent vibration or shank bending.
PPE: Always wear safety goggles and a dust mask. The high-speed chip removal can eject debris forcefully.
Q: Can this bit drill holes like a regular drill bit?
A: Yes! Thanks to the "Top Sharpening" design, it has active cutting edges on the tip, allowing it to bore straight down into the material before you start moving it sideways.
Q: What is the advantage of the bearing version?
A: The version with the top bearing allows you to place a template (pattern) on top of your workpiece. The bearing rides along the template, ensuring your switch box cutout is perfectly shaped every time.
Q: Is this bit suitable for metal?
A: No. This bit is designed for wood, wood composites, and plastics (PVC). Do not use it on ferrous metals, stone, or concrete.
