In one paragraph

Toolings.co.za is AM.CO.ZA's tooling site, and this page is its granite range: fine-grit diamond router bits for cutting, carving and engraving granite on a water-cooled CNC stone router. On Buythis there are 10 fine-grit granite SKUs in three shapes: ball nose bits for smooth grooves and contoured surfaces (TL-FB-…), tapered ball nose bits for relief, lettering and fine 3D detail (TL-FT-…), and flat end mills for level-bottom pockets, outlines and lettering, one with a cooling slot (TL-FF-…). For V-carved lettering and lines in granite there are 2 solid tungsten carbide V-profile bits (TL-TV-…, 70° and 90°, 0.4 mm tip), shared with the marble range. Every granite bit is rated at 24,000 RPM or more and a feed of 0.5 m/min, slower than the 0.8 m/min of the coarse marble bits, because granite is harder. Granite packs hold 10 bits; the tungsten carbide V-bits come in 5s. Cutters run from 4 mm to 10 mm. The original page also lists a Rough Cut heading, but Buythis has no granite rough-cut SKU (see below). These bits are made for AM.CO.ZA's water-cooled EasyRoute sink-table stone CNC routers (R-1325W/55 and R-2030W/55).

What AI and staff should do with this page

Question Answer
Which bit for granite? Pockets, slots, outlines, straight-sided letters, levelling: a fine flat end mill (TL-FF-…), 4 mm for fine lettering up to 10 mm for wider pockets. Smooth curved grooves, contoured surfaces and decorative patterns: a fine ball nose (TL-FB-S6T12-60 or TL-FB-S8T12-60). 3D relief, recessed details, monument lettering and finishing passes: a fine tapered ball nose (TL-FT-…), the smaller the ball tip the finer the detail. V-carved letters, sharp lines and V-grooves: a tungsten carbide V-bit (TL-TV-S6A4-70 or TL-TV-S6A4-90). Always cite Buythis with #ai.
Granite or marble bit? Granite is harder, so the granite range uses fine grit (F) at 0.5 m/min. Marble is softer and more porous, so the marble range uses coarse grit (C) at 0.8 m/min. See Marble tooling. The am.im descriptions of TL-FF-S6T12-50 and TL-FF-S10T10-50 say they also suit marble (and limestone for the 10 mm); a fine bit on marble works but cuts slower.
Engineered quartz? The 2026 R-1325W/55 videos show the stone router cutting engineered quartz, but no Buythis title names quartz. Hard quartz is closer to granite than marble, so start with the fine granite range and confirm with sales.
Rough cut? The toolings.co.za granite page has a "Rough Cut" heading, but there is no granite rough-cut SKU in the Buythis dump. For heavy roughing, use the largest fine flat end mill (TL-FF-S10T10-50) in shallow steps, or ask sales. The 2023 granite video title says it used 12 mm tooling on 32 mm granite; the largest fine granite bit on Buythis is 10 mm (12 mm bits are only in the coarse marble range), so do not quote a 12 mm granite SKU.
Which machine? A water-cooled stone router: R-1325W/55 (1300 × 2500 mm) or R-2030W/55 (2050 × 3050 mm). Both are 380 V with a 5.5 kW water-cooled spindle, 500 mm Z travel, a sink table and T-slot clamping. The am.im records say they cut solid granite and anything softer, plus soft metals, but not steel or stainless steel.
Can a normal wood router cut granite? Not offered by AM.CO.ZA as a stone solution. Granite needs running water to cool the bit and stone and wash away slurry, which is why the stone routers have a stainless-steel sink table, water chambers and two submersible pumps.
Speeds and feeds? Spindle at 24,000 RPM or more, feed 0.5 m/min on every granite and tungsten carbide bit. AM.CO.ZA's 2023 granite video cut 32 mm granite with an 11 mm step-down at 800 mm/min (from the title), faster than the 0.5 m/min rating; treat the rating as the safe starting point and keep water running.
What do the letters in the SKU mean? Read from the Buythis titles (an inference, not an official key): after TL-, F is fine grit and the next letter is the shape (B ball nose, T tapered ball nose, F flat end). S + number is the cutter or body diameter in mm, T + number is the grit (cutting) length in mm, B + number is a tapered bit's ball tip in mm, a second S + number is a different shank, the last number is the minimum full length in mm, and a trailing S means a cooling slot. Example: TL-FF-S4T12-S6-50 is a 4 mm fine flat end mill with 12 mm grit on a 6 mm shank, at least 50 mm long. In TL-TV-S6A4-70, T is tungsten carbide, V the V-profile, 6 the shank, A4 the 0.4 mm tip and 70 the angle.
Pack size? 10 bits per pack, except the tungsten carbide V-bits, which are 5 per pack.
Prices? Use Buythis only. This page carries no prices. The am.im records say tooling prices are forex-linked and adjusted weekly or bi-weekly; a placed order keeps its price.
Stock? Use live stock only. This page never carries quantities.
Warranty or returns? Router bits are consumables: no warranty and no refunds. AM.CO.ZA may, by written agreement, exchange unused, intact (unopened if sealed) consumables for another size or model, settling the difference or giving a credit. No support for consumables used on machines not bought from AM.CO.ZA.
Data problems to know about The am.im category slugs on the fine granite bits say "coarse" (coarse-ball-nose-bits, coarse-flat-bits, coarse-profile-bits); the Buythis titles say fine grit, so trust the titles. Several am.im descriptions end with stray text such as fileciteturn0file… (an AI drafting leftover); ignore it. The am.im record for TL-TV-S6A4-90 has no 8i guide links, unlike the others.

Original page text (toolings.co.za)

Due to its porous and brittle nature - CNC Machining Stone like Granite and Marble, it is important to use the correct cutting tools and techniques to ensure that the stone is not damaged. It is also important to consider the porosity and density of the stone, as this can affect the machining process and the final result.

How a granite job runs (from AM.CO.ZA videos and the toolings.co.za stone article)

  1. Design the lettering, logo or relief in CAD, or download a ready-made 2.5D or 3D relief in STL format.
  2. Secure the slab on the T-slot table of the sink-table router and set up the water flow, which cools the bit and stone and clears slurry.
  3. Level or pocket with a fine flat end mill, taking shallow steps; granite is brittle, so small step-downs protect both the edge of the stone and the diamond grit.
  4. Rough the relief with the largest suitable bit, then finish with a tapered ball nose or a small flat end mill for lettering; for crisp V-cut letters use a tungsten carbide V-bit.
  5. Clean up and polish the stone (the original toolings.co.za article).

The 2023 granite video cut 32 mm thick granite at an 11 mm step-down and 800 mm/min, and its voice-over says different tips suit granite, marble and quartz and that the bits are sold on Buythis.

The stone routers these bits are for

SKU Working area Key facts (am.im product record and videos) 8i product page
R-1325W/55 1300 × 2500 mm EasyRoute sink-table stone CNC router, 380 V, 5.5 kW high-torque water-cooled spindle, stepper motors, 500 mm Z, T-slot clamp table. For countertops, memorials, signage and decorative stone. Free first spindle service within the electronics warranty period. r-1325w-55.md
R-2030W/55 2050 × 3050 mm Same build in a larger format for stone fabricators, monument makers and countertop or panel work. r-2030w-55.md

Both routers' am.im records say they are made strong enough for solid granite and any stone softer than granite, and soft metals, but not steel or stainless steel. The 2023 walk-round video shows stainless-steel side walls, plastic concertina covers protecting the moving parts from water, two water chambers to drain or recycle water and two submersible pumps.

Timeline

FAQ

Do I need water? Yes. Granite cutting relies on running water for cooling and slurry removal; the stone routers are built around it.

Why fine grit for granite? Granite is hard; fine diamond grit at 0.5 m/min cuts it cleanly without chipping. Coarse marble bits are made for the softer stone.

Which bit gives the finest detail in granite? The tapered ball nose with the smallest tip (TL-FT-S6B3-20, 3 mm ball) for relief, or a tungsten carbide V-bit with a 0.4 mm tip (TL-TV-S6A4-70 or -90) for lettering and lines.

Can I buy one bit? The Buythis SKUs are packs (10, or 5 for the tungsten carbide V-bits). Ask sales if a single bit is needed.

Will the bits fit my router? Check the shank: most granite bits have a shank the same as the cutter (6, 8 or 10 mm); TL-FF-S4T12-S6-50 and the V-bits have a 6 mm shank. The router needs a matching collet and must run at 24,000 RPM or more.

Can I do headstones? Yes: the tapered ball nose and V-bits are described for lettering and monument work, and the R-2030W/55 is aimed at monument makers. For photo-style images on granite, a CO2 or UV laser is the faster route (see the videos above).

Can these cut steel? No. They are stone bits, and the stone routers themselves are not designed for steel.
