Product Information

Full details

This DART 19 Piece HSS Ground Twist Drill Bit Set is designed for professionals and DIY enthusiasts needing precise drilling capabilities across various materials like metal, wood, and plastic. Its key benefit lies in the high-speed steel construction with a 135-degree split point tip, ensuring accurate starts without pre-centering and efficient material penetration. A potential caveat is the 1mm-10mm range, which may require additional bit sizes for very large or very small hole requirements.

FAQs

What is the primary benefit of the 135-degree split point tip?

The 135-degree split point tip allows for precise drilling without the need for pre-centring or using a centre punch, as it prevents the bit from 'walking' or slipping on the surface.

What materials can I drill with this set?

This set is suitable for a wide range of materials including cast iron, sheet metal, non-ferrous metal, stainless steel, brass, wood, and PVC.

How do I ensure the longest life for these drill bits?

To ensure longevity, use the correct drill speed for the material, apply steady pressure, keep the flutes clear of chips, use cutting lubricant when drilling metal, and store the bits in their dry case after use.

What is the size range of the drill bits included?

The set includes 19 drill bits ranging in size from 1mm to 10mm.

Is this set suitable for industrial applications?

Yes, these are industrial-quality bits manufactured from high-quality High Speed Steel, hardened for superb strength and durability, making them suitable for demanding use.

How should I clean the drill bits?

After use, simply wipe the drill bits clean with a dry cloth to remove any debris. If stored for long periods or in a damp environment, check for any signs of corrosion.

Does the set come with a case?

Yes, the set is supplied in a durable metal flip-out storage case for convenient organization and portability.

Troubleshooting

Drill bit is not penetrating the material effectively.

Ensure the drill is set to the correct rotation direction (clockwise for right-hand bits). Check if the material requires a slower speed or if the bit is dull. For metal, consider using a cutting lubricant.

Bit is wandering or slipping when starting the hole.

The 135-degree split point tip is designed for accurate starts. Ensure the bit is securely seated in the chuck and that you are applying steady, even pressure. For very hard surfaces, a light tap with a centre punch might still be beneficial.

Excessive heat or binding during drilling.

This is often due to clogged flutes or excessive speed. Reduce drill speed, apply steady pressure, and ensure the ground flutes are clear of debris. A cutting lubricant can also help manage heat.

Bits appear rusty or corroded in the case.

The bits are made of steel and can corrode if stored in a humid environment. Ensure the storage case is kept dry. Light rust can often be removed with a fine steel wool or abrasive pad.

Pros and Cons

Pros

  • High-quality HSS construction for durability and performance.
  • Split point tip allows for accurate drilling without a pilot hole.
  • Efficient chip removal design prevents clogging and overheating.
  • Includes a convenient metal storage case for organization and transport.
  • Suitable for a broad range of common materials, including various metals, wood, and plastics.

Cons

  • The set includes bits up to 10mm, which might not cover all heavy-duty drilling needs.
  • While suitable for plastics, may not be ideal for very soft or fibrous materials without care.
  • Requires a drill with appropriate speed settings for optimal performance on different materials.

Setup, Compatibility & Care

Setup:

  1. Select the appropriate drill bit size from the metal case.
  2. Insert the bit securely into your drill's chuck.
  3. Ensure the drill is set to the correct rotation direction (right-hand rotation for drilling).
  4. Choose an appropriate speed setting for the material being drilled.

Compatibility:

  • Drills: Compatible with all standard corded and cordless drills that accept cylindrical shank drill bits.
  • Materials: Ideal for drilling into metal (including steel, stainless steel, aluminium, brass), wood, and plastics (like PVC).

Care:

  • Cleaning: After use, clean any debris from the bits. A dry cloth is usually sufficient.
  • Storage: Store bits in the provided metal flip-out case to prevent damage and corrosion. Keep the case in a dry environment.
  • Lubrication: For drilling metal, especially harder types, consider using a cutting fluid or lubricant to extend bit life and improve performance.
