WEASYFIX SDS-MAX Core Drill Bit – 55 mm x 1020 mm (F3)

The professional solution for foundation screw preparation

Weasyfix provides specialized accessories to guarantee professional results that are accessible to everyone. The SDS-MAX 55 mm drill bit is a critical tool for the first stage of foundation screw placement. It allows for the precise creation of pilot holes in stony or difficult ground conditions, ensuring that your foundation remains solid and durable over time.

Precision pre-drilling for maximum stability

Creating a pilot hole is an indispensable step for the correct alignment and secure seating of foundation screws. This operation requires high precision, as the depth of the hole must be slightly less than the intended depth of the foundation screw itself.

• Optimized diameter: At 55 mm, this drill bit provides the ideal diameter for foundation screw installation across various soil types.

• Exceptional reach: With a total length of 1020 mm, it allows for pre-drilling to a maximum effective depth of 900 mm in normal soil conditions.

• Effortless power: Weighing 3.8 kg, the bit is engineered to utilize the impact power of a rotary hammer to penetrate rocky ground without requiring excessive physical force from the operator.

• Industry compatibility: This bit is fully compatible with the Makita HR5212C and other professional-grade SDS-Max rotary hammers.

Key advantages:

• Foundation longevity: Ensures foundation screws are driven straight and securely.

• Rocky ground performance: Specialized for penetrating stony and dense soil profiles.

• Saves time: Rapidly creates deep pilot holes compared to manual methods.

• Heavy-duty build: A registered model designed for intensive site use.

Installation tips

• Depth accuracy: Always measure the required depth of your foundation screw before drilling. The pilot hole should be slightly shallower than the screw length to ensure the screw's threads "bite" firmly into the undisturbed soil at the bottom.

• Machine handling: Use a high-capacity SDS-MAX rotary hammer. Hold the machine firmly and let the weight of the tool and the bit do the work; avoid applying excessive body weight which can overheat the motor.

• Debris removal: Periodically lift the bit slightly while drilling to help clear loose soil and stones from the hole, preventing the bit from binding.

• Safety gear: Given the power of SDS-MAX machinery, always wear heavy-duty gloves, safety goggles, and hearing protection during operation.
