YOCAN 7-Piece High-Speed Steel (HSS) 4-in-1 Serrated Woodworking Drill Bit Set
[Product Overview]
Say goodbye to the hassle of frequently changing drill bits. The YOCAN Yujian 4-in-1 serrated drill bit combines four functions in one: drilling, routing, cutting and reaming. Whether crafting solid wood furniture, slotting panels or working with aluminium alloy sheets, a single drill bit handles it all.
The 7-piece set covers common sizes from 3mm to 10mm, meeting all requirements from precision drilling to larger-diameter machining.
【Key Features】
🔹 135° Fully Ground Cutting Edge — Sharp and Burr-Free
Featuring a 135° angled edge design, the cutting edge is sharp and wear-resistant, ensuring precise drilling. The fully ground manufacturing process ensures every edge is in optimal cutting condition, resulting in smooth holes, even grooves and no burrs.
🔹 High-Speed Steel (HSS) — High Hardness & Excellent Wear Resistance
Crafted from premium high-speed steel (HSS), this material offers high hardness and exceptional wear resistance, ensuring a longer service life compared to standard carbon steel drill bits. It exhibits outstanding heat resistance during high-speed operation, minimising the risk of annealing and deformation.
🔹 Sharp teeth — smoother cross-cutting
The unique serrated edge design not only facilitates effortless vertical drilling but also ensures smooth and efficient cross-cutting. Chip removal is smooth and jam-free, ensuring a seamless working experience.
🔹 Universal Compatibility — Suitable for Hand Drills, Impact Drills and Bench Drills
Compatible with a wide range of equipment, including hand drills, impact drills and bench drills. Note: As the drill rotates clockwise, please drill and cut in the opposite direction to the drill’s rotation during operation.

【Suitable Materials】
Recommendation Level Suitable Materials
★★★★★ Highly recommended Solid wood, blockboard, plywood, MDF, particleboard, fibreboard
★★★ Recommended (for drilling only, not for routing) Thin sheet metal, aluminium sheet, aluminium alloy
✘ Do not use Concrete, steel plate, tiles, glass
【Precautions for Use】
⚠️ Panel thickness limit: Suitable for cutting panels ≤3mm thick. If cutting panels thicker than 3mm, we recommend using a cordless drill rated at 36V or above, or a mains-powered drill with a power rating of 350W or above.
⚠️ Rotation direction: As electric drills rotate clockwise, please drill and cut in the opposite direction to the drill’s rotation during operation.
⚠️ Power recommendation: Cordless drills have lower speed and torque, which prevents the saw teeth from performing to their full potential. We recommend using a high-power hand drill or bench drill to achieve optimal performance from the saw teeth.
【Applications】
DIY Woodworking: Solid wood furniture making, model making, drilling and slotting in sheet materials
Home Renovation: Cabinet installation, fixing skirting boards, drilling holes for shelving
Thin Sheet Processing: Drilling and slotting in aluminium alloy doors and windows, thin sheet metal and plastic sheets
Working in Confined Spaces: In tight spaces where a cutting machine cannot be used, a serrated drill bit can be used to complete the cut
