Armeg 40mm Cobalt Vari-Pitch Holesaw – PCH040

The ultimate multi-purpose holesaw with 8% cobalt for longer life

• Stronger flex-free body construction is designed with high alloy content for structural integrity and tool dependability
• Teeth are manufactured with M42 superior steel featuring 8% Cobalt which provides excellent wear resistance at higher drilling temperatures for extended tool life
• Variable pitch cutting teeth combine an aggressive cut for increased spoil removal with a smoother cut for reduced vibration. This allows the holesaws to benefit from both increased cutting speed and tool durability
• Irregular depth clearance gullets avoid trapped spoil by providing a more efficient chip clearance meaning teeth stay sharper for longer

CVP Holesaws can be used in:

• Steel
• Stainless steel
• Non-ferrous
• Wood
• Plastics
• MDF

User Instructions

• Wear appropriate Personal Protective Equipment (P.P.E) when using holesaws
• Ensure holesaw is correctly attached to the relevant adaptor for your machine
• Use holesaw at the recommended speeds for the material being drilled as shown in the chart
• Use an appropriate cutting lubricant when drilling in steel
• After producing a hole, remove the “slug” of the material from the throat of the holesaw before commencing another hole
• After pilot drill penetration, be careful not the “bang” the holesaw onto the durface of the material to be drilled. This could damage or break the cutting teeth

Tech-Tip

• Our holesaws fit standard adaptors – please see our range of Holesaw Accessories for a tip on how to correctly fit your holesaw to your adaptor
