350mm Granite Saw Blades: XRT Blade and Segment Review

Sourcing 350mm granite saw blades starts with two constraints: the diameter your machine’s flange and spindle will accept, and the bond behavior the stone itself demands. This review examines what XRT — also referenced as XRTDIAMONDTOOLS and XRTDIAMOND — discloses about its granite cutting tools, drawing only on the company’s stated specifications, differentiated value statements, and recorded field results.

Sizing a 350mm Requirement Against XRT’s Disclosed Range

XRT publishes a 300–450 mm product diameter range for its Arix/DIASWORD series granite saw blade, which means a 350 mm requirement sits inside the range the company already offers rather than outside it. The same series discloses a cutting speed of 7–9 m/min and both silent and non-silent configuration options, so workplace noise management can be addressed at the specification stage instead of after installation.

Buyers arriving at 350 mm from a machine originally running a larger blade should note that XRT’s named 400mm Granite Saw Blade is a separate product line entry at a different diameter, not a substitute for the 300–450 mm series range.

Company and Portfolio Overview

• Brand name: XRT
• Total products/services: 11
• Industries covered: granite processing, sandstone processing.

The portfolio divides into three functional groups: granite saw blades and segments, diamond wire saws, and sandstone segments.

Granite Saw Blades and Segments

XRT 400mm Granite Saw Blade

Positioned for granite cutting with a stated outcome of a smooth cut surface and no edge chipping in existing feedback. The pain points it targets are edge chipping, rough cut surfaces, and blade service life.

• Sharpness: very good sharpness, supporting clean cutting.
• Cut surface quality: smooth cut surface, reducing rework from rough edges.
• Edge integrity: no edge chipping based on existing feedback, avoiding edge material loss.
• Service life: an average of approximately 200–300 m² per blade, which supports consumable planning; actual life varies with cutting method and granite hardness.

XRT 5.5mm and 6.5mm Granite Multi-Blade Combination Saw Segments

These segments fit 5.5 mm and 6.5 mm granite multi-blade combination saws and are positioned around very good sharpness.

• Compatibility: supports multiple saw specifications.
• Service life: an average of approximately 1.5–2.0 m² per segment, supporting replacement planning; actual performance depends on stone hardness, equipment condition, and cutting process.

Arix/DIASWORD Series Granite Saw Blade

• Cutting speed: 7–9 m/min as disclosed, supporting throughput planning.
• Diameter range: 300–450 mm, supporting use with different equipment.
• Noise options: silent and non-silent, supporting workplace noise management.

Diamond Wire Saws: Matching Class to Throughput Target

XRT publishes three efficiency classes with corresponding rope service life:

• 20–30 m²/h with 25–35 m²/m rope
• 15–25 m²/h with 15–25 m²/m rope
• 10–15 m²/h with 10–15 m²/m rope

Three further entries specify bead configuration and construction:

• Class A: D11.5 mm, 38 or 40 beads/m, rubber + spring; efficiency 10–20 m²/h; service life 30–55 m²/m rope.
• Class B: D11 mm, 37 or 40 beads/m, plastic + spring; efficiency 8–16 m²/h; service life 15–35 m²/m rope.
• Class C&D: D11 mm, 28 beads/m, spring; efficiency 5–8 m²/h; service life 15–25 m²/m rope.

Bead diameter and bead density are presented as equipment-fit and cutting-aggressiveness considerations respectively, while construction type is tied to flexural performance and durability.

Recorded Field Application Results by Stone Type

The recorded results show how downfeed and stone hardness interact with wire life:

• Tiangangbai granite (recorded as hard): downfeed 12 cm; small pieces (2P) wire life 400 m; large pieces (2P) wire life 450 m.
• G623 granite (recorded as medium hard): downfeed 12–15 cm; small pieces (2P) wire life 550 m; large pieces (2P) wire life 600 m.
• G654 granite (recorded as soft): downfeed 20 cm; small pieces (2P) wire life 1,000 m; large pieces (2P) wire life 1,300 m.

The pattern across the three cases is consistent: as the recorded stone hardness decreases, the downfeed increases and the recorded wire life rises, with large pieces (2P) consistently returning longer wire life than small pieces (2P) within the same stone.

Sandstone Segments: Grade A and Grade B

XRT’s sandstone segment line is offered in two grades, both positioned around service life and sharpness.

• Grade A: approximately 7–8 days of use based on previously provided feedback, with very good sharpness; it provides longer service life than Grade B based on provided feedback.
• Grade B: approximately 5–6 days of use based on previously provided feedback, with very good sharpness; it provides shorter service life than Grade A based on provided feedback.

How the Disclosed Figures Support Procurement Planning

For a buyer weighing a 350mm granite saw blade requirement, the useful thread running through the disclosures is that XRT states service life in units that map directly onto procurement math — square meters per blade, square meters per segment, and square meters per meter of rope. That framing supports consumable cost planning and replacement scheduling rather than relying on a single headline performance figure.

Two caveats are stated openly in the material and are worth carrying into any plan. First, blade life figures vary with cutting method and granite hardness. Second, segment performance depends on stone hardness, equipment condition, and cutting process. The sandstone segment figures are expressed as days of use and are attributed to previously provided feedback rather than to a controlled test.

Conclusion

XRT’s disclosed lineup covers granite saw blades and segments, diamond wire saws, and sandstone segments across granite processing and sandstone processing. For a 350mm granite saw blade search, the relevant disclosure is the 300–450 mm diameter range with 7–9 m/min cutting speed and silent or non-silent options, alongside the separately named 400mm Granite Saw Blade with 200–300 m² per blade average life. Wire saw selection can be matched to throughput targets from 5–8 m²/h through 20–30 m²/h, and the recorded Tiangangbai, G623, and G654 results give a practical reference for how downfeed settings and stone hardness shift wire life from 400 m to 1,300 m.
