Milwaukee Metal Drill HSSR D338 Set-19 Piece (4932352468)

Description

Genuine Milwaukee · Part no. 4932352468

A 19-piece set of Milwaukee HSS-R roll-forged metal drill bits to DIN 338, with a black oxide finish and a standard 118° point. It is the general-purpose set for steel, cast iron and alloyed or plain steels up to 800 N/mm²: brackets, mild steel strip, number plate holes and repairs around the garage.

Good to know

• Do I need to centre punch? Yes, a 118° point wanders more on starting than a 135° split point, so centre punch the hole first and start slowly.
• Will it drill stainless or hardened bolts? Those are often harder than the 800 N/mm² this set is rated for; use a cobalt bit for stainless, hardened steel and broken bolts.
• How do I keep the bits sharp? Drill steel at a slow-to-medium speed with steady pressure and cutting oil; squealing or blue chips mean too much speed or heat.

Which one?

For stainless and hard steel, the M. Drill Hss-Co 19 Piece Set CB (4932499764); for a tougher ground set, the M. Drill HSS-G TW 19 Piece Set CB (4932499766).
