Frequently Asked Questions (FAQs)

• What are hinge drill bits used for?
  Hinge drill bits drill pilot holes for fitting hinges and hardware to doors, cabinets, and furniture. The bit sits inside the screw hole of the hinge and guides the drill to the correct position. This produces an accurately placed pilot hole each time.

• What does HSS mean on a drill bit?
  HSS stands for High Speed Steel. It is a steel alloy that resists the heat generated during drilling. This allows the bit to stay hard and keep its edge at higher cutting speeds compared to standard carbon steel.

• Can hinge drill bits be used on MDF and manufactured boards?
  Yes. HSS hinge drill bits cut through MDF, plywood, and other manufactured boards. These materials are common in flat-pack and cabinet fitting work, where pilot hole accuracy matters most. Use a steady speed and avoid excessive pressure to keep the edges of the hole clean.

• What materials can HSS drill bits cut through?
  HSS drill bits cut through wood, plastic, and softer metals such as brass, copper, and aluminium. They are not suited to harder metals like stainless steel, which requires cobalt or carbide-tipped bits instead.

• What is the difference between a hinge drill bit and a regular twist drill bit?
  A standard twist drill bit requires manual positioning over each hole location. A hinge drill bit has a guide collar that fits inside the countersunk screw hole of the hinge. This directs the bit to the centre and produces an accurately placed pilot hole.
