Product Features
High-Quality Core Materials, Sturdy & Durable
The drill bit is made of high-quality tungsten carbide (tungsten steel alloy) material for the crosshead. The material has high hardness and strong wear resistance, which extends the product's service life from the source. It can easily cope with the drilling challenges of various hard materials and effectively reduce the trouble of frequently changing drill bits.
Precise Specifications & Wide Compatibility
The product uses a standard SDS Plus shank, highly adaptable for stable transmission. The drill bit is approximately 160mm long, balancing drilling depth and operational flexibility. The 9-piece set covers sizes from 5mm to 16mm — including 6mm (0.24"), 8mm (0.31"), 10mm (0.39"), 12mm (0.47"), 14mm (0.55"), and 16mm (0.63") — precisely matching different drilling needs without separate purchases.
Equipped with four precision cutting edges and a crosshead design for quick, smooth cutting; double-helix design optimizes the drilling path, improving chip removal and stability; the combination of double grooves and double holes with a round shank allows quick removal of drilling waste, preventing blockages while ensuring secure SDS Plus interface installation.
Widely Applicable & Ready to Use
No additional accessories needed — ready to use immediately. Easily matches common drilling equipment. Compatible with a variety of materials including clinker, concrete, bricks, natural stone, and artificial stone. Suitable for home decoration wall drilling, tile drilling, masonry structure construction, and more — accommodating both professional construction and DIY needs.
Frequently Asked Questions
QWhat sizes are included in this SDS Plus drill bit kit?
The kit includes 9 drill bits in the following sizes: 5mm (×2), 6mm (×2), 8mm, 10mm, 12mm, 14mm, and 16mm — covering the most commonly needed diameters for construction and renovation work.
QWhat type of shank does this drill bit set use, and what tools are compatible?
These drill bits feature a standard SDS Plus shank, which is compatible with most SDS Plus electric drills, rotary hammers, and drilling machines widely available on the market. No adapters or additional accessories are required.
QWhat materials can these drill bits be used on?
These drill bits are designed for hard materials and are suitable for drilling into clinker, concrete, bricks, natural stone, and artificial stone. They are ideal for applications such as wall drilling, tile drilling, and masonry structure construction in both professional and DIY settings.
QWhat makes the tungsten carbide tip better than standard drill bits?
Tungsten carbide (tungsten steel alloy) offers significantly higher hardness and wear resistance compared to standard high-speed steel (HSS) drill bits. This means the bits stay sharper for longer, handle tough materials more effectively, and reduce the frequency of bit replacement — making them more cost-efficient in the long run.
QHow does the double-helix design benefit the drilling process?
The double-helix design optimizes the chip removal path during drilling, which improves drilling stability and prevents hole position deviation or uneven hole diameters. Combined with the double grooves and double holes, drilling waste is cleared quickly to prevent blockages and maintain consistent drilling efficiency.
QAre the product dimensions exactly as listed, and is there a size tolerance?
The dimensions listed (e.g., drill bit length of approximately 160mm and diameter sizes) are based on standard specifications. However, due to manual measurement, there may be slight errors in individual product dimensions. These minor variations are within normal manufacturing tolerance and do not affect the performance or usability of the drill bits.
