English

cutting lubricant when drilling metals. The exceptions are

cast iron and brass which should be drilled dry.

nOTE: Large [5/16" (8 mm) to 1/2" (13 mm)] holes in steel

can be made easier if a pilot hole [5/32" (4 mm) to 3/16"

(5mm)] is drilled first.

nOTE: When using a cutting lubricant, be sure not to get

the lubricant on the tool.

Drilling in Wood

Start drilling with slow speed and increase to full power

while applying firm pressure on the tool. Holes in wood can

be made with the same twist drills used for metal. These

bits may overheat unless pulled out frequently to clear chips

from the flutes. Work that is apt to splinter should be backed

up with a block of wood.

Drilling in Masonry



WARNING: Never drill into masonry which is

reinforced such as rebar reinforced concrete.



WARNING: For applications which produce a

considerable amount of dust such as core drilling,

always use an auxiliary dust attachment with an M

Class rated dust extractor such as DWV902M.

Use dry core bits. Keep even force on the drill but not so

much that you crack the brittle material. A smooth, even

flow of dust indicates the proper drilling rate.

Use sharp drill bits only. For masonry, such as brick, cement,

cinder block, etc., use dry diamond core bits

nOTE: Always use core bits designed for dry drilling.

Troubleshooting Drilling in Masonry

Problem Solution

Core bit does not cut.

Material too hard for core bit.

• Choose a more appropriate core bit

(with softer segments).

Segments look glazed and polished • Drill in abrasive material to

re-expose diamond segments.

Dust accumulating in core bit.

Accumulating dust slows down the

drilling speed.

• Disengage drill bit regularly to

evacuate cuttings. Check filter on

dust extraction. Clean or replace

as required.

Rotating speed may not be

appropriate.

• Refer to the Maximum

Recommended Capacities for

proper speed ratings.

Segments wear too fast. • Choose a more appropriate core bit

(with harder segments).

• Reduce the pressure applied on

the core bit.
