Key Benefits & Features

• Unrivaled Expertise & Quality
  Trust the leader: Haglof Sweden has been manufacturing professional-grade increment borers since 1943, combining Swedish craftsmanship with cutting-edge materials and quality control.

• Extensive Range of Lengths 
  Available lengths range from 100 mm up to 1000 mm, with the ideal bit length roughly ½ to ¾ of tree diameter for optimal penetration.
  

• Core Diameters
  Standard core diameter is 5.15 mm, with other diameters available on request including larger 10 mm and 12 mm options for substantial sample extraction or fiber analysis.
  

• Thread Variants Tailored to Wood Type
  Choose between 2-thread (slower, more torque—perfect for hardwoods) and 3-thread (faster, smoother—ideal for softwoods or general use). The 3-thread engages up to 66% faster than 2-thread.

• Advanced Materials for Smooth, Long-Lasting Performance

  • Borer bits: Hardened Swedish steel with PTFE (Teflon) coating across models for low friction, rust resistance, and ease of insertion/extraction.

  • Extractor: Durable stainless steel with specially-shaped head and teeth for effortless core removal.

  • Handle: Iconic blue, grip-friendly plastic with a secure metallic lock for comfort, visibility, and safety in the field.

• Custom Configurations Available - Special Orders
  Mix and match lengths, core diameters, and threading to suit your specific trees, research goals, or field survey needs. Custom lengths and special coatings available on request, along with Large Core Borers with diameters up to 12mm, Send us an email and we'll help - sales@prospectors.com.au

• Easy Maintenance & Longevity
  Preserve performance with light oil cleaning, drying after use, and keeping the tool slide-free. If needed, steel wool can remove rust, and beeswax on the tip can ease next use. Never bore with the extractor in place—ensure it’s used only post-drilling.
