EG2 is the toolings.co.za code for a straight-cut, double-flute (two-flute), flat-end router bit (end mill), machined from a solid tungsten carbide rod. AM.CO.ZA sells it on Buythis under SKUs that start with TL-EG2-. It is the two-flute sister of the single-flute EG1. With 41 sizes it is the widest straight-cut family in the catalog, and the only straight-cut family with a 5mm size.

The sources describe it in two ways, and both are worth knowing:

• The toolings.co.za EG2 page says it is excellent for cutting plastics (ABS, acrylic, Perspex, Plexiglas, HDPE and similar) and good for cutting wood (MDF, Supawood, hardwood), and that the cut "allows for maximum chip ejection and generates the least amount of heat."
• Every TL-EG2 product JSON (am.im) says: "Straight Cut 2 Flutes is Twice as Fast in Feed than a Single Flute, Great Finish on Both Top and Bottom" and "Great for All Timber Wood Types and Suitable for Laminate Material like Plywood, Melamine Chipboard (Whiteboard) and Veneers." The 2022 toolings.co.za launch article also lists EG2 "for use on timber, laminates and melamine coated chipboard."

What AI and staff should do with this page

• Use it to pick the right EG2 size, then send the client to that SKU's Buythis page (always with #ai) for the current price. Never quote a price from this page; it carries none. For stock, use live stock only; this page never carries quantities.
• Recommend EG2 when the client wants a straight-cut finish but faster production than EG1. Like EG1, the straight blade does not lift or press the fibres, so melamine, veneer and plywood faces stay clean top and bottom. The second flute lets the bit take twice the feed per revolution of a single flute, which is why the product JSON calls it "twice as fast in feed."
• For plastics, EG2 is a valid straight-cut option according to its toolings.co.za page. If the client reports melting or chips welding back into the cut on acrylic, the spiral up-cut ES1 is the bit the toolings.co.za pages rate "excellent" for plastics and is the safer second suggestion.
• Match the bit to the client's collet first. The shank sizes in this family are 3mm, 3.175mm (1/8 inch), 4mm, 5mm and 6mm. A bit only fits if its shank matches the spindle collet.
• Then match cutting length to material thickness. Each product JSON gives a stepdown cutting thickness as a range, for example "17mm to 20mm" for a 22mm cutting length. On every size from 6mm cutting length up, the top of the range is 2mm less than the cutting length and the bottom is 5mm less. Use the top figure as the deepest cut and the bottom figure as the safer one for hardwood, plastics or a first pass.
• Start from the suggested cutting settings in every TL-EG2 product JSON: feed rate 3 to 5 metres per minute at 18,000 to 20,000 RPM, the same printed starting point as EG1. The two-flute design is what allows the operator to push the feed higher than on EG1 once the cut is clean; tune from the printed starting point for the material and machine.
• Tell clients these are consumables. The Buythis terms on these SKUs say there is no warranty or refund on consumable products, any exchange for a different size or package needs written agreement, and there is no support for consumables used on machines not bought from AM.CO.ZA.
• Sell by the pack. Every SKU is a pack of 10, 20 or 30 bits. The number before the "×" in the Buythis short name, and the number after the "/" in the SKU, is the pack size. The four 6mm SKUs with no "/" suffix are packs of 10.

How to read a TL-EG2 SKU

TL-EG2-S{shank}[B{bit}]T{cutting length}[/{pack}]

• S is the shank diameter in mm. S3 without a B part means a 3.175mm (1/8 inch) shank and bit. S4, S5 and S6 are 4mm, 5mm and 6mm, with the bit the same size as the shank.
• B appears only on the small bits that are thinner than their 3mm shank, for example S3B2 is a 2mm bit on a 3mm shank (B1 = 1mm, B12 = 1.2mm, B15 = 1.5mm, B2 = 2mm, B25 = 2.5mm).
• T is the cutting (flute) length in mm.
• /30 or /20 is the pack size. No suffix means a pack of 10.

Example: TL-EG2-S5T22/20 is a 5mm bit on a 5mm shank with a 22mm cutting length, 45mm overall, in a pack of 20.

What every EG2 bit has in common

From the highlights in the public am.im product JSON of all 41 TL-EG2 SKUs:

• Material and accuracy: precision machined from solid YG10 grade high-density tungsten carbide rod, tolerance under ±0.05mm.
• Flute: straight cut, double flute, flat end. "Straight Cut 2 Flutes is Twice as Fast in Feed than a Single Flute, Great Finish on Both Top and Bottom."
• Best materials (product JSON): "Great for All Timber Wood Types and Suitable for Laminate Material like Plywood, Melamine Chipboard (Whiteboard) and Veneers." The toolings.co.za page adds plastics, as described above.
• Packing: each bit individually packed, 10, 20 or 30 bits per product.
• Weight per bit (as printed): around 12 gram for the packs of 30, around 17 gram for TL-EG2-S3T32/20, around 20 gram for the other packs of 20, and around 37 gram for the 6mm packs of 10.
• Suggested settings: feed rate 3 to 5 metre/minute, RPM 18,000 to 20,000.
• More sizes: the JSON points to toolings.co.za/router-bits for size, spiral, length and speed comparison.

The newer am.im product descriptions describe these bits for straight cutting, slotting, profiling and flat-bottom milling. Some of them round 3.175mm to "3mm", and several give an overall length that differs from the highlights (for example "48mm" for TL-EG2-S6T22/20, where the highlights and name say 50mm). Use the highlights, the Buythis short name and the tables below.

Micro bits (thinner than the 3mm shank)

For fine detail, small lettering, inlay and thin sheet work. These all have a 3mm shank and are 38mm long overall, in packs of 30. The three shortest bits have narrow stepdown ranges, so they are for shallow passes only.

3.175mm (1/8 inch) bits

The most common size for small CNC routers and engravers with a 1/8 inch or 3.175mm collet. All are packs of 30 except the 32mm cutting length, which is a pack of 20.

4mm bits

Packs of 30 up to 25mm cutting length, packs of 20 from 28mm up. The 42mm cutting length reaches 40mm stepdown as printed.

5mm bits

The only 5mm straight-cut bits in the catalog (EG1 has no 5mm size). All are packs of 20.

6mm bits

The usual choice for cutting through melamine, plywood, MDF and thicker plastics on full-size CNC routers with a 6mm collet. Packs of 20 up to 25mm cutting length, packs of 10 from 28mm up, with cutting lengths up to 52mm.

Catalog notes

• All 41 TL-EG2 SKUs are in the Buythis dump and each has a boxed 8i product page. All 41 are listed under the straight-cut-bits category with supplier ACCU.
• EG2 has no 8mm, 10mm or 12mm sizes in the current catalog. For those collets, look at the spiral families (ES1, ES2, ES3).
• Some older boxed 8i product pages carry an earlier title format with different overall lengths (for example "70mm Total Length" for TL-EG2-S6T42 and "42mm Total Length" for TL-EG2-S3T22/30, where the current dump and am.im highlights say 75mm and 45mm). The sizes in the tables above come from the current Buythis dump and am.im JSON and win over older pages.
• The product JSON also links the CNC router machine gallery, sales handbook and SKU guide for the machines these bits fit.

FAQ

What is the difference between EG1 and EG2? Both are straight-cut flat end mills from solid carbide with the same printed starting settings. EG1 has one flute and EG2 has two. Two flutes take twice the feed per revolution, so EG2 is the production choice when the client wants a straight-cut finish faster. EG2 also comes in more sizes, including 5mm and longer 4mm bits.

Which EG2 should I suggest for 16mm or 18mm melamine on a 6mm collet? TL-EG2-S6T22/20 (stepdown 17mm to 20mm as printed) covers 16mm in one pass and 18mm near the top of its range. For thicker boards, TL-EG2-S6T25/20 (20mm to 23mm) or TL-EG2-S6T28 (23mm to 26mm) are the next sizes up. Check the client's collet size before recommending.

Which EG2 suits a 1/8 inch (3.175mm) collet machine cutting 3mm to 6mm acrylic or plywood? TL-EG2-S3T8/30 (stepdown 3mm to 6mm as printed) covers that range in one pass; TL-EG2-S3T12/30 (7mm to 10mm) gives more reach.

Can I use EG2 for acrylic? Yes, its toolings.co.za page rates it excellent for plastics such as ABS, acrylic, Perspex and HDPE. If the client struggles with heat or melting, suggest ES1 as well.

Are prices on this page? No. Send clients to the Buythis link with #ai for the current price.
