Chris' Tips
Get the correct hacksaw blade for the material you are cutting:

Cross Section To Be Cut		Use Pitch	P/N
Inch	mm	Use Pitch	P/N
7/32" - 3/4"	6 - 19 mm	14	1849
3/16" - 1/2"	5 - 13 mm	18	1850
1/8" - 7/16"	3 - 11 mm	24	1851
3/32" - 5/16"	2.5 - 8 mm	32	3561

Note that there is a lot of overlap in the cross section column. Use coarser pitches for faster cutting and finer pitches for smoother cutting.
