Specifications:

Upgrade your drilling rig to a dust-free system with the Johnson Tools Vacuum Dust Collector Adapter. Designed for professional electricians and HVAC installers, this adapter connects between your handheld drill and the diamond core bit, extracting hazardous silica dust directly from the source before it enters the air.

Why Use Our Dust Collector Adapter?

Health & Safety Compliance: Essential for indoor work. It captures up to 95% of airborne dust, keeping the job site clean and protecting you from inhaling concrete dust.
Standard M22-M16 Fit: Features an M22 Female thread (to connect to your drill motor) and an M16 Male thread (to connect to standard diamond core bits).
360° Swivel Hose Port: The outer housing rotates independently from the drill shaft, ensuring your vacuum hose stays untangled and positioned conveniently while you drill.
Precision Centering: Includes a slot for a Pilot Drill (Center Bit), allowing you to start your hole accurately without the bit wandering on the wall.

Product Name: Vacuum Dust Collector

Thread Specification: M22 Female - M16 Male

Q1: Will this fit my core drill?

A: This adapter fits drills with a standard M22 Male spindle. Please check your drill's manual. It converts the connection to M16 Male for the core bit.

Q2: Do I need a special vacuum cleaner?

A: We recommend a Class M or Class H industrial vacuum cleaner for concrete dust. The adapter port is designed to fit standard vacuum hoses.

Q3: How does the pilot bit work?

A: The pilot bit (usually a taper shank) fits into the center of the adapter. You use it to start the hole. Once the core bit has cut a groove (about 5-10mm deep), you simply remove the pilot bit and continue drilling with just the dust collector attached.

Q4: Can I use this for wet drilling?

A: This specific model is designed for Dry Drilling to extract dust. For wet drilling, you would typically use a water swivel adapter instead.
