1. Product Specification
This M14 Hole Saw 8PC Set is a professional vacuum brazed stone drilling combo developed for wet drilling work on stone, tile, ceramic and glass materials. Every core bit within the M14 Hole Saw 8PC Set is equipped with standard M14 female thread shank, which can fit all 100–125mm angle grinders directly for quick assembly and stable clamping force. The M14 Hole Saw 8PC Set adopts exposed orderly arranged diamond grit cutting edge paired with anti-rust steel body, delivering fast water flushing chip removal and consistent sharp cutting performance during long-duration continuous wet drilling operations. The M14 Hole Saw 8PC Set includes 8 complete mainstream drilling sizes: 6mm, 8mm, 10mm, 25mm, 32mm, 35mm, 50mm, 68mm, fully covering all daily renovation, pipeline installation and countertop hole-making demands. Each core bit of the M14 Hole Saw 8PC Set undergoes rigorous torsion, abrasion and cutting smoothness quality control testing before packaging, making the M14 Hole Saw 8PC Set a reliable all-size drilling solution for professional tile installers, stone fabricators and DIY renovation workers.

2. Craft & Performance
All core drill bits of the M14 Hole Saw 8PC Set are manufactured via high-temperature integral vacuum brazing technology, the core production process that ensures extended service life and balanced steady cutting efficiency of the M14 Hole Saw 8PC Set. The open exposed diamond grit layout on each cutting head of the M14 Hole Saw 8PC Set forms wide uniform drainage gaps, rapidly washing away stone, ceramic and glass powder with cooling water and effectively preventing grit clogging and uneven one-sided abrasion during non-stop long-hour drilling work. The anti-rust electrostatic protective coating on thickened 45# steel body of the M14 Hole Saw 8PC Set acts as a barrier against water and corrosive mineral slurry, avoiding surface oxidation and rust even under persistent humid wet construction environments. The seamless vacuum brazed fusion structure securely locks diamond grit in place to stop partial grit shedding under high-speed rotation and heavy torque load. The solid thickened steel base resists bending and drilling deviation, producing smooth burr-free round holes while greatly lowering the risk of brittle tile and stone edge chipping. All eight bits of the M14 Hole Saw 8PC Set share a unified short 60mm body design, allowing operation inside narrow confined gaps that oversized drilling tools cannot reach, significantly boosting the scene adaptability of the M14 Hole Saw 8PC Set for complex residential and commercial decoration projects.
Application
The multi-size functional M14 Hole Saw 8PC Set is an essential power tool accessory for tile installers, kitchen countertop fabricators, home renovation contractors and amateur DIY stone and glass processing enthusiasts. The eight matched core bit sizes equipped in the M14 Hole Saw 8PC Set can create precise neat holes on glazed tile, vitrified tile, polished tile, marble, granite, quartz stone, artificial stone and glass when used with adequate water cooling. At bathroom, kitchen and custom stone processing construction sites, tradesmen rely on the M14 Hole Saw 8PC Set to drill faucet mounting holes, sink cutouts, pipeline through-holes and small fixture fixing holes on wall and floor stone slabs. The compact uniform length design of every core bit in the M14 Hole Saw 8PC Set grants access to tight narrow gaps inaccessible to large-format drilling equipment. All bits of the M14 Hole Saw 8PC Set feature universal M14 thread, compatible with all mainstream angle grinders without requiring extra conversion adapters. Whether indoor residential tile remodeling, commercial shop stone decoration, outdoor garden hardscape paving or small custom countertop fabrication, the complete eight-size combination of the M14 Hole Saw 8PC Set satisfies all regular wet hole-making requirements without separate individual purchases of single-size drill bits.
Advantages
1. Complete 8 Practical All-Size Integrated Combo: The M14 Hole Saw 8PC Set includes eight mainstream drilling diameters covering tiny pilot holes to large sink openings, eliminating extra separate procurement costs for multiple single-size drill bits.
2. Open Exposed Diamond Grit Wet Drilling Structure: The M14 Hole Saw 8PC Set features exposed diamond grit layout for fast water flushing chip removal, anti-clogging and consistently smooth stable wet cutting performance.
3. Anti-Corrosion High-Durability Protective Coating: The M14 Hole Saw 8PC Set combines rust-proof protective coating and exposed diamond cutting layer, balancing long-term wet drilling anti-rust performance and sharp high-efficiency cutting capacity.
4. Standard M14 Universal Thread Interface: Every core bit of the M14 Hole Saw 8PC Set uses M14 female thread for direct plug-and-play installation with 100–125mm angle grinders with no adapters needed.
5. Thickened 45# Steel Vacuum Brazed Integrated Structure: The M14 Hole Saw 8PC Set adopts heavy-duty solid 45# steel substrate with full vacuum brazing treatment, resisting twisting and grit shedding under continuous heavy drilling load.
6. Authorized Industrial Safety Certification: The full M14 Hole Saw 8PC Set passes CE & EN 13236 industrial safety certification, operating with low vibration to reduce cracking risk of fragile tile, glass and stone materials.
FAQ
Q1: What materials can the M14 Hole Saw 8PC Set process?
A1: The M14 Hole Saw 8PC Set fits glazed tile, vitrified tile, polished tile, marble, granite, quartz, artificial stone and glass; it is not suitable for thick steel-reinforced concrete.
Q2: What power tools match the M14 Hole Saw 8PC Set?
A2: All core bits of the M14 Hole Saw 8PC Set adopt standard M14 internal thread, directly compatible with all 100–125mm angle grinders, no extra conversion adapter required.
Q3: Can the M14 Hole Saw 8PC Set be operated fully dry without cooling water?
A3: Short intermittent emergency dry drilling is permitted, but continuous sufficient water cooling is highly recommended for the M14 Hole Saw 8PC Set to extend service life and prevent tile or stone cracking.
Q4: Can I customize the appearance and packaging of the M14 Hole Saw 8PC Set for bulk wholesale orders?
A4: Yes. As the original manufacturer of the M14 Hole Saw 8PC Set, we provide full OEM & ODM customization including drill body color, private brand logo printing and personalized packaging for global hardware importers and cross-border merchants.
