MAKITA D-21777 Bi-Metal Hole Saw 83 mm (3-1/4 in)

Hole Saw MAKITA D-21777 BIM 83 mm (3-1/4 in)
Makita hole saw, SKU D-21777, is an 83 mm hole saw from the Bi-Metal Hole Saw (BIM) series, serving as a standard cutting tool for professional tradespeople requiring versatile multi-material capability: Bi-Metal Material: Teeth are manufactured from tough, sharp High-Speed Steel (HSS) for efficient metal cutting. The cylinder body is constructed from flexible shatter-resistant steel to prevent cracking and shattering under heavy use. Variable Pitch Tooth Design: Utilizes a 4/6 TPI variable tooth pitch design. This design is key to reducing vibration during drilling, resulting in smoother cuts, less heat buildup, and extended saw life. Cutting Depth: Capable of a maximum cutting depth of approximately 39 mm to 42 mm. Application: This product includes only the hole saw cup (arbor and pilot drill bit not included). Users must purchase a suitable arbor corresponding to the hole saw size to attach to a power drill.
