2-Piece Stepped Pagoda Chamfer Core Drill Bit Set

Take your tiling and masonry projects to the next level with this professional-grade 2-piece stepped pagoda drill bit set. Engineered from industrial-grade carbide alloy steel, these chamfer core drill bits are built to handle the toughest surfaces — from thin glass tiles to thick granite slabs — with speed, accuracy, and clean, chip-free results.

Made in Mainland China.

Key Features

• Industrial-Grade Carbide Alloy Construction: Maintains cutting precision even after 300+ drilling cycles on reinforced concrete and hard stone, delivering long-lasting, reliable performance on demanding job sites and DIY projects alike.
• Progressive Step Design (20mm / 35mm / 50mm): The three-stage pagoda step profile lets you complete sink cutouts and pipe perforations in a single pass — no pre-drilling required, no tool swaps mid-task.
• 50% Faster Debris Removal: The multi-layer drill tip combined with the innovative three-stage hole-expansion geometry clears debris up to 50% faster than conventional core drills, dramatically reducing edge chipping on delicate surfaces like glass and marble.
• Universal Shank Compatibility: Fits most standard rotary drills straight out of the box. Professionals and DIY enthusiasts can get drilling immediately — no adapters needed for the majority of common drill chucks.
• Versatile Surface Penetration: Cuts cleanly through 9+ surface types, including 6 mm glass tiles, ceramic, porcelain, marble, granite slabs up to 80 mm thick, reinforced concrete, and more — ideal for home renovations, bathroom remodels, kitchen installs, and construction projects.

Frequently Asked Questions

Q: What materials can these stepped pagoda drill bits cut through?

A: These carbide alloy stepped pagoda core drill bits are capable of cutting through 9+ surface types, including glass tiles (from 6 mm), ceramic, porcelain, marble, granite (up to 80 mm), reinforced concrete, and other hard masonry surfaces — making them ideal for bathroom and kitchen tile installations, countertop cutouts, and construction work.

Q: Do I need a special drill to use these bits?

A: No. These chamfer core drill bits feature a standard shank that fits most rotary drills available on the market. Both professional contractors and home DIYers can use them right away without needing special adapters or additional equipment.

Q: How do the three steps (20mm, 35mm, 50mm) work?

A: The pagoda-style step design progressively expands the hole in three stages — 20 mm, 35 mm, and 50 mm — within a single drilling operation. This allows you to achieve your target hole diameter efficiently without pre-drilling a pilot hole, saving time and reducing the risk of cracking or chipping the surrounding material.

Q: How many holes can I drill before the bits wear out?

A: Thanks to their industrial-grade carbide alloy construction, these drill bits maintain cutting precision for 300+ drilling cycles on reinforced concrete. Actual longevity will vary depending on material hardness, drill speed, and whether water cooling is used during drilling.
