Đặc trưng

• Unique chip shape improves metal bite.
• The use of a two-stage blade ensures smooth discharge of chips.
• Securely cut the nail without being bitten.
• Composite materials and layered plates can be penetrated with one shot.
• Use of the guide bar does not enlarge the center hole, and drilling of metallic siding using galvanic steel sheet can be performed cleanly and safely.
• ALC (especially wet ALC) also perforates smoothly without clogging the chips.
• Use an electric motor with a clutch for safety. (As much as possible, be careful not to push the clutch too far.)
• Use a polyclick guide bar for drilling metal siding using galvanic steel plates.
• If the cutter cuts into the hole during drilling, remove the center drill from the shank before drilling.
