Coated solid carbide drill for excellent stability

Ideal combination of drill geometry and carbide composition for exceptional performance on a wide range of drilling applications

Applications & Features

DrillingSmall-diameter drillingCoolant hole

1. New coated grade with highly improved wear resistance

• New coated carbide grade with a high level of versatility. Perfect grade for stable and long tool life on a wide range of materials.

2. Innovative cutting edge offers reliable drilling

• Non-conventional edge shape reduces cutting forces and improves adhesion strength of the coating to prevent sudden edge breakage.

3. World-wide standard shank style – Standardized with DIN6535-Form HA

• Only 6 shank size diameters available – ø6, ø8, ø10, ø12, ø14, ø16 mm. This reduces the number of collets required.

1. Variety of dimensions and L/D

• Allows deep hole drilling up to 5 to 15 times the drill diameter.
• Available as standard items from ø0.1 to ø3.0 mm in 0.01 mm increments. Shank diameters are all unified to ø3 mm.

2. Center drills for machining guide hole

• DSM-CP140 type has a 140° point angle which can effectively prevent the cutting edge from chipping.
• DSM-CP90 type, which has a 90° point angle, can be also used for chamfering of the hole mouth.

  • The cutting parameters shown in the table are merely a starting guideline for general machining. Values should be varied depending on the power or rigidity of the machine to be used. Optimum conditions should be selected depending on the actual chip control or damage on edges.
  • When using the smaller diameter tools in each range, set the feed “f” to the lower recommended values.
  • The coolant supply is critical for the provision of stable machining conditions and enhanced tool life. A large coolant volume should be supplied, especially when drilling difficult-to-cut materials.
  • When drilling stainless steel with low machinability such as austenitic stainless steel with a depth deeper than L/D = 3, a pecking cycle or internal coolant supply is recommended.

  • When using the smaller diameter tools in each range, set the feed “f” to the lower recommended values.
  • Oil holes that become blocked may cause drill breakages. A fi lter to prevent the circulation of chips must be used on the coolant supply system.

※ Not recommended

  • When the drilling depth is deeper than L/D = 5, use drill pecking every 10 to 50% of the drill diameter.
  • The above cutting conditions are applied to when a water soluble cutting fluid is used. For drilling a hole smaller than ø0. 3 mm, use of a starting drill is recommended.
  • When setting the drill, the drill runout should be within 0.002 mm on the taper. (Especially for the drill diameter smaller than ø0.5 mm)
