Improved safety and drilling speed.

• Higher cutting performance for reinforcing bars.
• Drilling through deck plates.
• Drilling holes close to a perfect roundness.
• More accurate hole starting without bit walk.
• Triple thread is used. (the delta-shank types are used for drill bits with a small diameter.)
• Limited circumferential wear.
• The least amount of vibration when drilling minimizes workers' fatigue.

• Concrete, block, mortar, stone, brick, concrete-placed deck plate, etc.

	Bit diameter:	o 3.2mm to 22.5mm
	Overall length:	See size table.
	Max. drilling depth:
	Applicable electric drill:	Light-weight hammer drills

• Power of cordless hammer drill; thread shape suitable for rotation rate.
• The same characteristics as the general Deltagon bit SDS-plus except for the thread shape.

• Concrete, block, mortar, stone, brick, concrete-placed deck plate.

	Bit diameter:	o 3.2mm to 6.0mm
	Overall length:	See size table.
	Max. drilling depth:
	Applicable electric drill:	Cordless hammer drill
