Precision Engineering for Delicate Surfaces

Whether you're installing a bathroom shelf, mounting tile décor, or working on intricate renovation projects, these spear-point drill bits deliver clean, chip-free holes with professional finish quality.

Each bit in the range features a precision diamond-ground tip, providing a sharp spear-head that penetrates smooth surfaces with minimal pressure.

Usage Tips:

• Lubrication is Key:
  Always use water or cutting fluid as a coolant to reduce friction and prevent overheating. This significantly prolongs the lifespan of the drill bit.

• Low Speed, High Control:
  Drill at low speeds and apply gentle pressure. Let the bit do the work — do not force it into the material.

• Mark the Spot:
  Use masking tape on smooth surfaces to mark your drilling point and avoid slipping at the start.

• No Hammer Action:
  Ensure your drill is in standard rotary mode. Hammer action can damage the bit and crack the material.

• Start Small:
  If drilling large holes, begin with a smaller size bit and gradually work up.

FAQs:

Q1: Can I use these bits on tempered or laminated glass?
A: No. Tempered glass is designed to shatter under stress and cannot be drilled safely with any bit.

Q2: What drill setting should I use?
A: Set your drill to low speed and rotary mode only. Avoid hammer or impact settings.

Q3: Can I use them with a cordless drill?
A: Yes, these bits are compatible with both cordless and corded rotary drills.

Q4: How do I prevent the bit from slipping on glass?
A: Stick a piece of masking tape over the area to be drilled. It helps guide the bit and prevents slipping at the start.

Q5: Do I need to cool the bit while drilling?
A: Yes, frequently dipping the bit in water or spraying the drill site helps keep the bit cool and extends its lifespan.
