Makita HB22S Metal Core Drill Bit 22x25mm

Special Features

• High-quality HSS material: Manufactured from High-Speed Steel for reliable performance and a long service life when used correctly
• Standard Weldon shank: Compatible with all common core drill machines featuring a Weldon connection, including the Makita HB500
• Compact S-variant: The “S” in the part number stands for Small, with a drilling depth of 25 mm. Ideal for thin metal
• Recognizing optimal chip formation: For maximum efficiency and a longer drill life, you should drill at the correct speed. Correct chip formation is visible as long metal strands. If the chips are short and small, the speed is too high or too low and needs to be adjusted
• Cutting oil required: This core drill bit must always be used in combination with cutting oil. This significantly extends the drill bit’s service life
• Rust protection: The drill bit has been pre-treated with oil to prevent rust during transport and storage
