Pack Quantity: 3

Shank Diameter: 1/4″ Hex

FEATURES

• Step drills are ideal for drilling into the following materials: – Ferrous and non-ferrous sheets metals, profiles and pipes. – Copper, brass and aluminium. – Stainless steel. – Plastics. – Maximum material thickness 4 mm. – To ensure best lifetime we recommend the use of a coolant.
• Trades: – Electrical: drilling of panels and cabinets for cable gland installation. – Plumbing / HVAC: access holes for pipework and installation. – Metal workers / fabrication: various sizes and hole enlargement. – Automotive: holes for cable installation (mobile telephones, antennas, re-directing electrical wiring). – Maintenance repair operations: various applications, sizes and hole enlargement.
• Step Drill advantages over conventional drill bits: – One drill bit to drill multiple sizes – Do more carry less! – Best option for enlarging existing holes. – More durable than twist drill bits, thick core resists breakage. – More accurate and less walking, tip starts on contact. – Clean burr free holes, less reaming required. – Drills plastic without splitting or cracking.
• Spot drill – Drill – Deburr – All in one go
• Rapid Strike tip for improved centering – less walking and fast drilling without the need to punch or pre drill the material.
• Special tip and step geometry for jam-free performance – less risk of drill snagging when used with high speed cordless tools and also prevents deformation of the drilled material.
• Optimised 2 flute ground sharpened edge geometry for 2 x faster and smoother cutting.
• Produced from custom engineered steel with black oxide coating for 4 x longer life.
• Optimised for use with high speed cordless drills.
• Laser engraved size markings for best long term visibility.
• Each step is relief ground to drill and deburr automatically.
• With 3 flat secure grip to prevent step drill from slipping in the chuck and ensure maximum transmission of torque.

Features

• The odd-numbered design with 4-6 teeth per Tpi with a positive tooth angle of 10° offers the following advantages: – Faster and more aggressive cutting
• Better heat dissipation during cutting? Teeth stay sharper longer
• Deeper curved grooves between the teeth provide more efficient chip evacuation, preventing clogging and temperature rise
• Specially selected tooth angle has a lower tendency to shrink thinner materials
• Teeth are alternately spaced on the sides, minimizing viscosity and friction
• Low shifting pressure due to a combination of aggressive tooth geometry and efficient chip removal
• This requires less force when drilling
• Serrated section of the hole saw is made of the best Matrix II high speed steel
• Matrix II steel contains 8% cobalt
• This means that the teeth retain their original hardness even at high operating temperatures during metal cutting.
• High-speed steel teeth are laser-welded to high-alloy steel housing
• The teeth are then vacuum cured at 65 HRC at 600°C to ensure maximum durability and performance
• The high wear resistance of Matrix II steel makes these saws excellent for cutting difficult and hard materials, such as stainless and acid resistant steels, as well as for cutting softer materials, such as wood.
• Hole saw body 1.27 mm thick steel and it retains its shape while being flexible
• The effective cutting depth is 41 mm
• Back plate construction, the plates are made of strong steel so that the holes do not get bigger over time. Strong backs increase durability and rigidity while minimizing vibration
• 4 drive holes for easier attachment to the mandrel
• The perfectly designed round back plate is especially important for hole saws with a larger diameter
• The angled grooves help to remove and extrude the core
• Application, high quality manufacturing technology guarantees high speed accuracy and hole saws are therefore suitable for both manual drilling and stationary use (manual hand only)

Specifications

• This range of high quality hole saws is the perfect solution for cutting in all types of materials
• Steel hardness up to 1000 N/mm2
• stainless and acid-resistant steel – non-ferrous metals – cast iron – aluminum – wood – medium density chipboard (MDF) – gypsum board – laminated board – PVC
