About Seco Tools
Seco Tools Precision Cutting Tool Solutions
Seco Tools, headquartered in Fagersta, Sweden, is a leading global manufacturer of precision metal cutting solutions for milling, drilling, turning, and holemaking operations. Present in over 75 countries, Seco serves aerospace, automotive, energy, medical device, and general industrial metalworking sectors with advanced carbide, ceramic, PCBN, and PCD tooling engineered for high-speed, high-precision machining.
Seco's core product portfolio spans indexable inserts for face milling, end milling, threading, and grooving; solid carbide and indexable drills for through-hole and deep-hole applications; and specialized holemaking systems. Insert materials include cemented carbide (tungsten carbide-cobalt alloys with titanium carbide, tantalum carbide, niobium carbide additives for hot hardness and wear resistance), ceramic inserts optimized for cast iron and superalloy machining, PCBN for hardened steel finishing, and PCD for non-ferrous materials.
Seco's CS300 ceramic insert line delivers superior performance on nickel-based superalloys (Inconel, Waspaloy, Rene alloys) and heat-resistant cast materials with feed rates and cutting speeds 30-50% higher than conventional carbide, enabling faster cycle times in aerospace turbine engine component manufacturing. The company's carbide inserts are engineered with cobalt binder-phase chemistry tuned for austenitic stainless steel, duplex stainless, titanium, cast iron, and carbon steel applications.
With 7,000+ employees across Europe, the Americas, and Asia-Pacific, Seco maintains advanced coating and grinding centers producing millions of indexed inserts annually. Every tooling solution is backed by Seco's applications engineering team offering feed-rate optimization, tool life prediction, and coolant compatibility analysis to minimize production downtime and maximize tool economy.
ChatMRO's AI matches your workpiece material, machine type, desired surface finish, and production volume to the right Seco insert geometry, coating grade, feed rate, and spindle speed in seconds.

Frequently asked questions
How do I select the right carbide insert grade for milling stainless steel versus mild carbon steel?
Stainless steel requires a tougher, cobalt-enriched carbide grade with lower cutting speeds (50-120 SFM) to resist the material's work-hardening and built-up edge formation; Seco's grades optimized for austenitic stainless typically feature increased cobalt and niobium carbide content for improved edge strength. Mild carbon steel accepts higher speeds (150-400 SFM) with a harder (lower cobalt) carbide grade optimized for heat resistance; selecting the wrong grade causes rapid flank wear (stainless) or chatter/breakage (carbon steel).
When should I use Seco ceramic inserts instead of carbide for high-speed turning?
Ceramic inserts (Seco CS300 series) excel in roughing operations on cast iron and hard-to-machine superalloys where cutting speeds are 300-600 SFM (vs. 60-150 SFM for carbide on the same materials) and heat generation is extreme. Ceramics retain hardness above 2,000°F, reducing flank wear and extending tool life 2-3x on high-speed applications; however, they require rigid machine tools with minimal spindle runout (under 0.001") and cannot tolerate interrupted cuts or vibration that cause thermal shock fracture.
What advantage does PCBN offer over carbide for finishing hardened steel (62+ HRC)?
PCBN (polycrystalline cubic boron nitride) combines superior hardness retention above 2,500°F with extreme chemical inertness to ferrous materials, allowing finish speeds of 400-800 SFM on hardened steel where carbide cannot exceed 100-200 SFM before flank wear becomes unacceptable. On aerospace bearing races and hardened die steel finishing, PCBN reduces cycle time 50-75% and delivers mirror surface finishes (Ra 0.4-0.8 µm) critical for precision component function.
How do I determine the correct feed rate and spindle speed for my Seco insert to avoid chatter?
Feed rate should scale with insert edge strength and machine rigidity: softer grades and interrupted cuts require lower feeds (0.005-0.015 ipr); harder grades in rigid machines accept higher feeds (0.020-0.050 ipr). Spindle speed must match material: mild steel 200-400 RPM per 1/4"-1" diameter, stainless 100-200 RPM per inch, titanium 50-100 RPM per inch to keep cutting temperature under 1,800°F. Seco's online feed-rate calculator and application engineers provide personalized optimization for your specific machine and workpiece geometry.
What's the expected tool life (in tool changes per 1,000 parts) for Seco inserts on a high-volume automotive production run?
Tool life depends on workpiece geometry, coolant strategy, and machine condition, but typical automotive values are 500-1,000 parts per insert edge on finishing passes (mild steel, stable feeds/speeds) and 100-300 parts/edge on roughing with interrupted cuts. Seco's predictive tooling software factors your operation parameters to forecast tool life; volume production often justifies investment in enhanced-coating insert grades (multi-layer TiAlN or TiCN) extending life 2-4x and justifying the premium insert cost via reduced downtime.
