Question 1

What is the difference between AlTiN and TiN coating on carbide end mills?

Accepted Answer

AlTiN (Aluminium Titanium Nitride) withstands cutting temperatures up to 900°C and is ideal for dry machining steel and stainless steel. TiN (Titanium Nitride) is a general-purpose coating rated to ~600°C, suitable for softer steels and general machining. For UAE workshops running stainless, Inconel, or alloy steel, AlTiN is the recommended choice.

Question 2

How many flutes should I choose for machining stainless steel?

Accepted Answer

For stainless steel (ISO M group), 4-flute end mills are the standard recommendation — they balance chip clearance and surface finish. In slotting operations where chip evacuation is critical, a 3-flute design may be preferred. For finishing passes with high-speed spindles, 6-flute end mills deliver superior surface finish.

Question 3

Can I buy cutting tools in the UAE with AED invoicing?

Accepted Answer

Yes. SAN Tools is a UAE-registered supplier stocking carbide end mills, inserts, and tooling locally in the UAE. All purchases are invoiced in AED, making us ICV-programme eligible for ADNOC, EDGE Group, and other government-related entities that require In-Country Value reporting.

Question 4

What is the recommended cutting speed for a solid carbide end mill in carbon steel?

Accepted Answer

For solid carbide end mills with AlTiN coating in carbon steel (ISO P group), recommended peripheral cutting speed (Vc) is 80-150 m/min. For a 10mm end mill at 100 m/min, that translates to approximately 3,183 RPM. Feed per tooth (Fz) should start at 0.02 mm/tooth and be adjusted based on machine rigidity and depth of cut.

Question 5

What is the minimum order quantity for carbide end mills from SAN Tools?

Accepted Answer

SAN Tools supplies carbide end mills with a minimum order of 1 piece — there is no minimum order quantity requirement. We serve individual CNC programmers, workshops, and large B2B procurement teams. Request a quote for volume pricing on orders of 10 pieces or more.
