Applications for Kyocera
SGS Precision Tools

These drills are ideal for high-temperature machining environments such as automotive parts, aerospace, medical devices, and mold manufacturing. When working with difficult-to-machine materials like stainless steel, heat-resistant alloys, or titanium, wear and breakage can significantly increase costs.

Kyocera SGS Precision Tools' solid carbide drills feature a carbide substrate that combines hardness and toughness, coated with Ti-NAMITE® to resist wear and oxidation under high temperatures. This combination of substrate and coating helps prevent edge chipping and ensures long tool life.

Extended tool life and stable machining reduce the need for frequent replacements and rework, cutting down on tool and scrap costs. Improved operational efficiency also helps lower the overall cost per part.

※Actual results may vary depending on the product and machining conditions such as spindle speed, feed rate, coolant, and machine rigidity.

How to Choose Kyocera SGS Precision Tools Carbide Drills

Cross Holes and Angled Surfaces

Recommended: Series 142P

If your application involves cross holes, angled exits, thin walls, or curved surfaces, Series 142P is designed to maintain hole accuracy even when tool alignment is difficult.

Its four-margin design provides strong guidance inside the hole, helping improve straightness and roundness. The Ti-NAMITE®-X coating also supports wear and chipping resistance under high temperatures, heavy loads, and continuous high-speed machining.

Best Suited For

• Cross-hole drilling
• Angled exits and curved surfaces
• Thin-wall parts
• Steel up to 45 HRC
• Titanium alloys up to 45 HRC
• High-carbon and medium-carbon steel
• Copper alloys

Available Lineup

• Cutting diameter: 3.0–19.05 mm (approx. 0.118–0.750")
• Cutting length: 15.0–238.0 mm (approx. 0.591–9.370")
• Overall length: 62.0–319.0 mm (approx. 2.441–12.559")
• Flute length: 20.0–266.0 mm (approx. 0.787–10.472")
• Shank diameter: 6.0–20.0 mm (approx. 0.236–0.787")
• Coating: Ti-NAMITE®-X

General Production Drilling

Recommended: Series 135

If you need a versatile drill for mass production, Series 135 is designed for efficient drilling across steels, stainless steels, heat-resistant alloys, titanium alloys, and hardened steels up to 45 HRC.

Its 145° notched point helps the drill self-center, reducing the need for a separate spot drilling operation. This can shorten setup time while lowering thrust and deflection during high-feed machining.

Available in 3×D and 5×D lengths, Series 135 covers a wide range of shallow to moderately deep hole applications.

Best Suited For

• General production drilling
• High-feed machining
• Applications where spot drilling should be reduced
• Steel and stainless steel up to 45 HRC
• Heat-resistant alloys
• Titanium alloys up to 45 HRC
• Hardened steel up to 45 HRC

Available Lineup

• Cutting diameter: 0.39–23.41 mm (approx. 0.015–0.922")
• Cutting length, 3D: 2.8–110.0 mm (approx. 0.110–4.331")
• Cutting length, 5D: 2.0–68.0 mm (approx. 0.079–2.677")
• Overall length, 3D: 38.0–178.0 mm (approx. 1.496–7.008")
• Overall length, 5D: 38.0–152.0 mm (approx. 1.496–5.984")
• Shank diameter: 3.18–25.4 mm (approx. 0.125–1.000")
• Coating: Ti-NAMITE®-A

Stainless and Titanium Alloys

Recommended: Series 143M-S

If you machine materials prone to welding, seizing, or galling, Series 143M-S is designed for stainless steel, heat-resistant alloys, and titanium alloys.

Its offset double-margin design reduces contact with the hole wall, helping control frictional heat and adhesion. This supports stable hole quality and longer tool life in difficult-to-machine materials.

The compact diameter and length range also make it suitable for high-volume production where reliability and repeatability are important.

Best Suited For

• Stainless steel up to 45 HRC
• Heat-resistant alloys
• Titanium alloys up to 45 HRC
• Applications prone to welding or galling
• High-volume production
• Operations requiring stable tool life

Available Lineup

• Cutting diameter: 3.0–19.05 mm (approx. 0.118–0.750")
• Cutting length: 36.0–50.0 mm (approx. 1.417–1.969")
• Overall length: 62.0–153.0 mm (approx. 2.441–6.024")
• Flute length: 20.0–101.0 mm (approx. 0.787–3.976")
• Shank diameter: 6.0–20.0 mm (approx. 0.236–0.787")
• Coating: Ti-NAMITE®-A
