Drillco annular cutter details
Drillco 1‑5/16 Annular Cutter 1" DOC (91SE220)
Drillco 91SE220 1‑5/16" Annular Cutter – 1" Depth of Cut is designed for high-efficiency broach cutting of large diameter holes. Constructed from high-speed steel (HSS) with premium-grade cobalt, this cutter removes only the periphery of the hole, ejecting a slug at the end for faster penetration, lower energy use, and reduced thrust. Ideal for industrial and professional workshop applications, it provides precise, clean, and efficient holemaking.
1‑5/16" diameter with 1" depth of cut for precise holemaking
Premium-grade cobalt construction allows milling of harder materials and runs about 10% faster than standard HSS
Center cutting tip suitable for plunging, pocketing, and holemaking
Multiple flutes (4 or 6) produce a superior surface finish and minimize chatter
Bright finish enhances cutting efficiency and reduces heat buildup
Round shank with 1 flat ensures secure attachment in compatible tools
Made in USA for consistent quality and reliability
Precise cutting reduces rework and improves hole quality
Durable cobalt construction extends tool life and lowers replacement costs
Efficient chip removal ensures smoother operation and less vibration
Versatile for profiling, grooving, contouring, and industrial fabrication
