Silverline Titanium Coated HSS Drill Bit Mixed Size 17pc Set 633829

Silverline Titanium Coated HSS Drill Bit Mixed Size 17 Piece Set 633829

Barcode: 5055058190291

MPN: 633829

Overview:

Titanium Coated HSS Drill Bit 17 Piece Mixed Size Set 633829 a practical everyday kit for drilling common sizes in metal, plastics, fibreglass and wood. Each bit is manufactured from high speed steel and titanium coated to improve wear resistance and help maintain cutting performance over repeated use. Supplied in a durable hard storage case with size-specific slots, it keeps your bits organised and easy to identify at a glance—ideal for workshop, site and DIY jobs. For best results and longer bit life, start with a smaller pilot hole and work up to the final size, using the correct speed and steady pressure for the material.

Applications

• Drilling mild steel and common alloys (bit and method dependent)

• General drilling in plastics and fibreglass

• Natural and man-made wood drilling

• Pilot holes, clearance holes and stepped drilling for accuracy

How to Use

• Mark the hole position and centre punch metal where needed

• Start with a smaller bit (pilot) for best accuracy and less stress on larger bits

• Use suitable speed: slower for metal, faster for wood/plastics (task dependent)

• Apply steady pressure—avoid forcing to reduce heat and wear

• Clear swarf regularly and use cutting fluid on metal where appropriate

• Store bits in the case after use to protect cutting edges

Titanium HSS Drill Bit 17pc Set – Key FAQs

• What materials are these drill bits suitable for?
  These titanium coated HSS bits are ideal for metal, steel and alloys, plus plastics, fibreglass and natural or artificial wood, depending on the application and technique.

• Do titanium coated bits last longer than standard HSS?
  Titanium coatings are designed to improve wear resistance and help maintain cutting performance, which can extend working life compared with uncoated HSS when used correctly.

• Why does the set include two 1mm bits?
  Small bits are commonly used and easier to snap if overloaded, so the duplicate 1mm bit provides a spare for frequent fine drilling tasks.

• Should I drill a pilot hole first?
  Yes. Starting small and stepping up reduces load, improves accuracy and helps extend bit life—especially in metal and harder materials.

• Do I need cutting fluid when drilling metal?
  It’s recommended for many metal drilling jobs to reduce heat and improve tool life. Use appropriate lubricant and keep speeds controlled.

• Are these bits suitable for masonry?
  No. For brick or concrete you should use masonry/TCT drill bits. This set is HSS for metal, plastics and wood.
